Should be titled: "Performance Tuning". No need for the word "Arch" and the word "performance" is more of a typical, generic search word that "speed". Or "Maximizing Performance". ````

Fan and buy ram?

"Things kinda slow? Buy more ram!" is really not the kind of advice anyone is looking for. And the CPU section (undervolting, etc.) isn't related to speed improvements, except fan control. This section is sorely lacking a link/howto to/for BFS.
--Gog 20:36, 24 October 2009 (EDT)

To my knowledge keeping the CPU cool does not improve performance so I removed this part. I also removed the introduction about RAM. So, problems solved ?

I'm not an expert, but doesn't overheating decrease performance? If it is, then preventing overheating should count as maximizing performance. If not, then the section is indeed irrelevant. I found this article saying it does for pentium 4 processors: http://www.xbitlabs.com/articles/cpu/display/p4-temp.html . But as I said I'm no expert, so what do you think?

The desktop switcheroo

Section "The desktop switcheroo" does not make sense. manolo 16:35, 7 November 2009 (EST)

Light weight desktop does improve performance of running app. -- Fengchao (talk) 05:07, 15 March 2013 (UTC)

libcrc32c

The section on btrfs talks about the libcrc32c module, but confusingly lists modules that don't seem related to btrfs. I think the zlib module is necessary, but have not yet figured out which others are or are not. Nitmd 23:27, 14 May 2010 (EDT)

Gone. Close. -- Fengchao (talk) 05:07, 15 March 2013 (UTC)


fps

What is with the advice about glxgears framerates? "less than 300fps"... It syncs with the monitors vertical refresh rate, meaning it will only go ~60fps (or whatever your refresh rate is). PIMPinator 11:29, 29 September 2010 (EDT)

Removed. Close. -- Fengchao (talk) 05:07, 15 March 2013 (UTC)

LZO for btrfs

I read about LZO compression and space_cache for btrfs lately: http://www.phoronix.com/scan.php?page=article&item=btrfs_space_cache --Longint 18:53, 15 June 2011 (EDT)

Firefox profile

Firefox profile guided optimization link is useless since firefox stock builds have it enabled. There's no more a relative section in Firefox --Flu 13:46, 29 September 2011 (EDT)
