- diggapleaze, on 10/12/2007, -2/+47The story mentions that you can disable Java in openoffice to improve performance (while losing some features). It's not mentioned *how* to do that though, so I thought I'd add in some instructions here:
1. start up openoffice (writer, for example)
2. go to Tools->Options
3. in the options tree on the left-hand side of the panel, navigate to OpenOffice.org->Java
4. uncheck the box that says "Use a Java runtime environment"
5. close all openoffice windows and restart
You should notice a very considerably fast start up time. Mine starts up in under 1 second. I haven't yet found any features that I'm missing due to disabling Java, but YMMV. Just keep in mind that OO.o is being designed/refactored to run without Java for (get this) portability reasons. - manitoba98xp, on 10/12/2007, -1/+18If you believe there will be trouble, please detail it. Otherwise, your comment is meaningless.
- jsully, on 10/12/2007, -4/+17Articles like this are the reason IPV6 is taking so long to adopt. The problem with telling people turn it off, is that they will...
- cynicist, on 10/12/2007, -1/+13There is absolutely no reason to disable ipv6, most applications like firefox default to ipv4 unless an ipv6 network is detected.
- Sairgem, on 10/12/2007, -1/+11We're fanboys because you can't backup your statement? ha.
- mitrovarr, on 10/12/2007, -1/+11It's also worth noting that this increases the speed at which openoffice loads in any operating system, including windows (sped up my windows system from about 6 seconds to 1.)
- Aliarse, on 10/12/2007, -1/+9Please do not feed the troll...
- arjie, on 10/12/2007, -2/+10Thanks a lot for that. My writer starts in 3.4 seconds with that disabled as opposed to 7.4 without (second start).
- malkir, on 10/12/2007, -1/+9Yeah I'm pretty sure any performance gain perceived is purely imagination.
- MrTea, on 10/12/2007, -1/+9Which features are lost exactly?
- aprice2704, on 10/12/2007, -1/+8Thanks, about halved my start time too :) Great little tip.
- sishgupta, on 10/12/2007, -1/+8Also IPV6 disables automatically unless you have an IPV6 router....
- ahirreddy, on 10/12/2007, -1/+8@auzy
"...Some of these tips have to be some of the biggest fanboy retardness ever..."
"...or its bragging about WPA support for instance..."
"...Apple's Airport extremes do support it already (even tunnelling, out of the box)"
Ya, talk about fanboys, I really hate them!
/sarcasm
Apple airport extreme: Overpriced, mid-range performing wireless router, although a great looking one. - damentz, on 10/12/2007, -1/+7Most users should not set swappiness to 0, there are times to when using the swap file is beneficial, especially when you are running very large programs, or large amounts.
sysctl -w vm.swappiness=20
Use that instead - inactive, on 10/12/2007, -2/+7@ispep:
You automatically think that everyone who uses ubuntu are fanboys and that they're better than everybody else? That's pretty a pretty crude remark. I use ubuntu, but I don't think I'm better than people who don't. I just like it because it works for me. I don't shove it down people's throats and act elitist regarding the matter.
Hey auzy, it's true I don't know ***** about basic computer science, but I don't need to. I just learn what I need to know to install and use ubuntu by reading manuals and asking well thought-out questions. I use my computer for work, not to gloat over what I know.
You guys are free to disagree all you like, but you shouldn't have to be a bunch of ***** while you're at it. - sishgupta, on 10/12/2007, -1/+6Amazing tip. Thank you!
- brutimus, on 10/12/2007, -1/+6I just turned off Java in NeoOffice (OpenOffice variant for osx) and it shaved probably 10+ seconds off the startup time on my MacBook Pro. Haven't noticed any missing features yet.
- inactive, on 10/12/2007, -2/+7@ispep:
No, I called you an ***** because you were rude and condescending. Again, you automatically assumed that I am a fanboy based on the assumption that I only use Ubuntu, which is false. I have used Red Hat, Fedora, and Mandrake. I had to read up a bit to learn those.
I repeat, I called you two ***** because you were rude and condescending (If I was unable to take criticism I should be in a psych ward by now). Not because you made a statement against Ubuntu. It's a free country. You can criticize anyone and anything you want to, but you should do it in a a proper manner.
So, just by your definitions, I, sir, am not a fanboy. I do suggest we end this conversation now. - ibis, on 10/12/2007, -1/+6Mainly all the wizards (does anyone use these?) and the database engine used by Base.
- ibis, on 10/12/2007, -1/+5Does anyone actually have ipv6 from their ISP? Me having it turned on in my OS isn't going to change that.
- ssam, on 10/12/2007, -1/+5there i a great illusion when checking optimisation.
1) open an application
2) close the application
3) do anything
4) open the application again
the second time you open the application it will be much faster. even if you stood on your head for step 3.
this is because the second time you start an application most of the files it needs are cached in ram.
so if you want to check if these optimisations work, make sure you restart after making the change. - cmost, on 10/12/2007, -4/+8Once again, this is BETA SOFTWARE!!! These sorts of articles are best kept until Ubuntu Feisty has been officially released. Last time I checked, that wasn't going to be until April 19th. Let's get a grip people.
- ibis, on 10/12/2007, -1/+5"Why would modifying hosts speed anything up when the entries are cached anyway"
Because recently they changed from using 127.0.0.1 for localhost and hostname, to using 127.0.1.1 for hostname. However some applications still try to look for hostname at 127.0.0.1. These take a few seconds to timeout (since it isn't there anymore) and it slows things down. - trogdoor, on 10/12/2007, -1/+4justnick:
I had the same exact problem I had 16 second load times on a high speed connection ( Yes, I am not exaggerating, I timed it ) instead of just disabling ipv6 I decided to look into what exactly , but what I found out is that the problem was not with my router as much as it was with my DNS server, was causing the problem, long story short, it was DNS _not_ my router ( well, sort of, but that's a whole other problem ) and switching to openDNS http://www.opendns.com/ solved my problem. Disabling ipv6 worked also, but using openDNS I have great speed ( faster than just disabling ipv6 as I have the added small benefit of openDNS being fast ) and I still get ipv6 to boot. Try looking into it, most times when people disable ipv6 to speed things up, a bad configuration is the real culprit. - ibis, on 10/12/2007, -1/+4And swappiness is about whether you would prefer to use your RAM to hold an app that isn't being used currently or as file cache. There are valid reasons for preferring both, hence it is tunable. Personally I can live with the performance hit from less file cache to get rid of the annoying lag when an app that has been swapped out has to be reloaded.
- feralkid, on 10/12/2007, -2/+4Don’t let the word "Beta" lead you into thinking this is a flakey distribution. This is not your MS style Beta where mysterious crashes occur and things stop working for no apparent reason. Think more along the lines of Gmail Beta which worked very well from day one. Alternatively I think it is quite valid to think of Feisty as just a really nice update to Edgy.
I've been running it as my primary desktop machine for some time and haven't encountered any issues. I still run Edgy on my laptop (main workhorse) and Debian lives on all my servers, but Feisty is a really nice update to Edgy and I'm looking forward to the final release.
As far as Beta releases its extremely stable. - NtrmDscrptr, on 10/12/2007, -1/+3Pay special attention to the "MOZ_DISABLE_PANGO=1" step!!
By putting the above quotation (sans quotes) in your /etc/environment, and restarting X, you will solve the Mozilla Thunderbird composition window cursor navigation bug, which has been plaguing the program since Dapper.
This is the bug where your cursor jumps to the beginning or end of a line when you use the [up] or [down] arrow keys. - mrsteveman1, on 10/12/2007, -2/+4Jesus stop fighting about stupid crap.
Suse already does parallel booting, and it can be setup for prelinking as well with a few clicks.
I've been managing networks for a long time, and I'm quite sure you gain nothing by using 2 loopback IPs with the same hostname pointed at them, the hostname was already pointed at 127.0.0.1 anyway, and that entry is at the top so it gets checked first.......the first entry that matches the query causes the application to skip the rest of the list.
Also, IPV6 should be disabled because its useless at the moment, and for some firewalls it represents a huge security hole. There is no reason to leave it on, at all. - Stemp, on 10/12/2007, -1/+3April 19th

Sorry for feeding the troll, I can't resist refuting thse ridiculous glaims. I am certainly no Linux guru, but I have used Mandrake (before it was Mandriva), Debian, CentOS, Fedora, OpenBSD, FreeBSD, PC-BSD, Slackware, Gentoo, and multiple derivatives thereof. Please don't make sweeping generalizations - mrsteveman1, on 10/12/2007, -0/+1yea......you shouldn't be binding servers to a local hostname anyway, its unnecessary.
- fragglet, on 10/12/2007, -0/+1The fact that he describes the profile option as "an option to grub" demonstrates pretty effectively that this guy has no idea what he's talking about.
- clickwir, on 10/12/2007, -0/+1You also describe it as an "option" so if this is incorrect.... do more than just berate him. Offer the correct info.
- Leomarth, on 10/12/2007, -0/+1Anyone know what exact day in April FF is coming out?
- Ozymandias42, on 10/12/2007, -0/+1I haven't heard someone recommending LVM as a speed boost on a desktop machine before. Is it that great?
- ssam, on 10/12/2007, -0/+1there have been bugs for which disabling ipv6 has helped. something to do with dns and buggy routers i think.
so for 90% of people disabling ipv6 will do nothing. but if you are getting very slow name resolution then it might help a lot - Auzy, on 10/12/2007, -2/+3I have IPV6, and anyone else with a proper setup and a 802.11n apple airport extreme do too.
And if its speeding it up at all, it means you must be using really crappy networking equipment with bugs in it.. I've never heard of it helping a single one of clients - inactive, on 10/12/2007, -0/+1That's an example of why people need to check out "tweaks" before they implement them.
- dtfinch, on 10/12/2007, -1/+1You may also see an improvement from installing and properly configuring a caching dns proxy like pdnsd, or configuring Firefox to cache dns responses longer than 60 seconds (the default), and more than 20 responses altogether.

- fragglet, on 10/12/2007, -0/+0It's an option to the kernel, not to grub. Get a clue.
- leeDav, on 10/12/2007, -1/+1Excellent guide, interesting too!
- srouquette, on 10/12/2007, -0/+0I think it's mid-april (around the 16)
- mgigirey, on 10/11/2007, -0/+0I wrote this about swappiness http://www.serbuntu.net/ubuntu/tips/swappiness
- justnick, on 10/12/2007, -2/+2ipv6 caused my network speed to crawl. I have a belkin wireless router. would take 10 seconds to load Google. Turned off ipv6 and it loads it up instantly. Turning off ipv6 is helpful in some circumstances. If your Internet pages load up fine, leave it on. If they load slow as hell (you will notice), then turn it off. I am all for moving forward with ipv6 but I don't want my network to run like ***** why I am waiting for it to take off. Also, I don't want to buy another router because of something like this that I can work around.
- theantix, on 10/12/2007, -1/+1Setting the vm.swappiness to 10 on my laptop increased performance in an amazingly drastic way. I have 2G of ram and this made me feel like I had an entirely new Firefox and Gnome-Terminal in particular seem to benefit the most.
- suppressingfire, on 10/12/2007, -3/+3Not only that, but being less swappy means there's less room for the file cache which can hurt performance, too.
- aprice2704, on 10/12/2007, -3/+3I just set mine to 10 and it seems to have made quite a big difference, so the 0 setting may not be much extra benefit anyway.
- hoolio87, on 10/30/2007, -1/+0Awesome article! Thanks!
http://hoolios.blogs.io/ - inactive, on 10/12/2007, -2/+1Not sure if this is a bug or intentional behavior, but I found that if you bind MySQL to the local 127.0.0.1 address, you won't be able to reach the server (port 3306 by default) from other computers. Other server apps may behave similarly, so be careful when aliasing your hostname to 127.0.0.1...
