- leszek, on 10/12/2007, -0/+13"24. hotplug and hotplug-net - activating hotplug subsystems takes time. I'd consider to turn them off."
It is not a good idea to turn hotplug off (all your usb device won't be detected when plugged). - Jammer, on 10/12/2007, -6/+15What's with all the people complaining about Ubuntu articles on Digg?
Your god ... not mine. - inactive, on 10/12/2007, -0/+8Unless it's an older drive (Which at 10 gigs, it probably is). It could be that the motors are old, it has a low RPM, or that there are sectors failing.
Also, if it's a machine as old as that hard drive probably is, it's going to be slow because, well, it's older than hell. - terribly1, on 10/12/2007, -0/+7I suggest leaving off suggestion 69 ("Add at least 2 exclamation points to the end of your sentences to indicate haste and importance.")
- inactive, on 10/12/2007, -2/+9Never too late.
If you run into problems, the support is incredible. - beermad, on 10/12/2007, -7/+14If you're going to recompile your kernel, there are a few extra flags you can add to the Makefile's HOSTCFLAGS and HOSTCXXFLAGS lines that will give you a massive speed boost.
1. Change -O2 to -O3
This is controversial and goes against every recommendation, but I've optimised my kernels to this level for several years and never suffered any problems because of it. I've found that programs can run twice as fast with the kernel optimised to this level.
2. Add -funroll-loops
Although this doesn't speed things up as much as increasing optimisation, it still makes a significant difference. This works because for() loops in C are very inefficient, so wherever the compiler finds a hard-coded number of iterations in a loop it changes it to that number of copies of the loop's contents
3. Add -ffast-math
Only a small speed-up but still worthwhile. - azdruid, on 10/12/2007, -0/+7I use Gentoo, and everything you have just said goes against The Rules Of Good Sense. Sorry. Try again.
- bcardarella, on 10/12/2007, -0/+6It might if there is alot of swapping going on.
- astroman74, on 10/12/2007, -0/+5Does this only work on the Ultimate version of Ubuntu? I think I'm screwed I bought the Home Premium version...
- Avalontor, on 10/12/2007, -0/+4The Ultimate Ubuntu Guide, not a chance. The 1/2 dozen Ultimate Ubuntu Guides I perused last week on digg were more of the Ultimate type then this one.
- jellyroll713, on 10/12/2007, -2/+6God all I want is for them to fix xine DVD playback. The AV sync issue drives me nuts.
- Ademan, on 10/12/2007, -0/+41 out of 3? Just wondering where did you get that number from? I've had no problems with 4 different wireless cards, maybe I'm just that lucky, or maybe you're full of *****...

Mmm, rice - inactive, on 10/12/2007, -6/+9Well if your going to be a ricer, just use gentoo.
always use -O2 and no extra flags, except possibily fomit-frame-pointer
its probably a placebo effect, i use to use gentoo, but now i use arch linux - manitoba98xp, on 10/12/2007, -0/+3What benefits are there to recompiling a kernel myself instead of using a stock Ubuntu one? I've heard mixed reports. Also, how would this affect other modules I install via APT? Would this still occur if I were to base it on the Ubuntu kernel sources instead of the vanilla ones? Help!
- jrocklin, on 10/12/2007, -0/+2you should try swiftfox - it's compiled for your processor and does provide some speed improvements. At least, it did on my P4.
- justnick, on 10/12/2007, -0/+2If you are talking about actual web browsing being slow, it could have something to do with Ipv6 and your router. To fix that goto your network settings and under the domain services (I think) and remove all things that have Ipv6 in the name. Also open a terminal and type "sudo gedit /etc/modprobe.d/blacklist" and add a line to the end of it that says "blacklist ipv6". save the file and restart the computer.
I had that problem with my belkin wireless router. It runs like a champ now. - bmartin, on 10/12/2007, -1/+3Here's something Ubuntu-related I haven't seen on Digg. Would you rather see more Windows articles? How about how Aero stacks up w/ Beryl? Sorry if this one is old, guys, but I thought it was a pretty fair comparison. I cut past the blog for you: http://www.metacafe.com/fplayer/434675/windows_vista_aero_vs_linux_ubuntu_beryl.swf
I'm sorry that you don't like Ubuntu. Did you at least give it a try? If you tried it and didn't like it, that's cool. - skatterbrainz, on 10/12/2007, -1/+3Geez. Enough with the !!!! already
- ajifans, on 10/12/2007, -0/+2a) There's a GUI for who can use SUDO.
b) There are numerous easy guides to configure all of those things. A GUI option would be nice but it's certainly not a dealbreaker.
c) Suse and redhat have inferior package management systems to Ubuntu. The former are nice and flashy but it takes a fraction of the time to add repositories and install packages on Ubuntu compared to SLED and RHEL. - Ngai, on 10/12/2007, -0/+1Mirror if it goes down. Thanks for the tutorial.
http://thelastcloud.com/nu/joos.rtf - petdance, on 10/12/2007, -0/+1Clearly, the title does not say it all, if you had to say more about it.
- TuringTest37, on 10/12/2007, -0/+1These tweaks are not reasonable for a non-programmer/uber-geek. I'm not an ubuntu user myself (Mac OS X here) but my very good friend (a non-programmer/uber-geek) installed "dapper" two weeks ago and was immediately struck by how slow her network access had become, compared to Windows XP. A little googling around and she discovered that disabling IPv6 support (in Firefox and elsewhere) made all the difference. Here is one thread that talks about what to do: http://ubuntuforums.org/showthread.php?t=6841
- alex0r, on 10/12/2007, -2/+3No, the size of the HD doesn't influence speed.
- xyphur, on 10/12/2007, -1/+2a) Windows wireless drivers for your card(s)
b) Ndiswrapper
Usually adding the two together will result in a functioning wireless adapter under Ubuntu. Although, I haven't had any luck with my Broadcom-based USRobotics USR5420 USB 802.11g adapter... I'm unlucky like that though, and it seems to render everyone else's otherwise undetected adapters functional, so your mileage may vary considerably from mine. - thelastknowngod, on 10/12/2007, -2/+3of course the 2.6.x kernels replace hotplug with udev. even if it didnt (assuming youre using gnome) nautilus automounts everything you plug into it.
- djchester, on 10/12/2007, -1/+2No benchmarks to prove the performance boost. Looks like the author is guessing. No digg.
- bmartin, on 10/12/2007, -0/+1@ajifans: While I agree that repo adding is much quicker in Ubuntu, the thing I miss most is Fedora's repos. They might have been a pain to add (unless you had a prebuilt RPM to use, like Livna or FreshRPMs, which you could add with a single RPM), but they were always up-to-date. Wine, Battle for Wesnoth, and Pioneers, and Amarok have all been out-of-date when I've grabbed them in the past; often, packages are much older than their Fedora counterparts.
- MrRuckus, on 10/12/2007, -6/+6I love Arch Linux.
- weizbox, on 10/12/2007, -0/+0If your going to go ahead and try to tweak out your Linux distro, it might as well be something other than Ubuntu, which is a more out-of-the-box working distro packed with tons of software and drivers, which is really great when you need something that 'just works', but if you want a system you can play around with more, and really tweak, Id suggest getting something else.
The instructions listed on this page are very well written out, and easy to follow.... and if you can follow those, you should be able to install some other distros where you can change more things around, more easily. Personally, I use Gentoo, and its great for system tweaking and optimizing, but probably isn't the best idea for someone who is just starting Linux for the first time (all though going through the install process alone will teach you tons). - mrsteveman1, on 10/12/2007, -2/+1Ubuntu is crap without a good configuration system for basic ***** like who can use sudo, changing the screen config, etc.
Until ubuntu has a good config system, opensuse and redhat enterprise linux are much more usable, both have robust configuration and management panels, especially opensuse. - inactive, on 10/12/2007, -1/+0***** Ubuntu
- r55741, on 10/12/2007, -9/+4my god why haven't I switched to ubuntu
- fuckingusername, on 10/12/2007, -13/+4any info of how to get 1 out of 3 wireless cards to work?
- reed311, on 10/12/2007, -14/+5Yeah, the OS is so user-friendly that there has to be 25 front page stories every day about how to actually make it work with your programs or have it run properly.
- dmron, on 10/12/2007, -17/+6Wow a ubuntu article on digg, who would have ever expected that!
- NX910a, on 10/12/2007, -11/+0My Firefox is quite slow, is it because I'm running Ubuntu on a 10GB HD? Probably, right?
- asiegrist, on 06/20/2009, -21/+4What is it with all the unbuntu articles on digg, my god...
