[Bug 429036] Re: core i7 i5 (Lynnfield) turbo boost not working

[Bacchus]

Also worth mentioning, ext4 performance has been suffering due to some
kernel regressions. (Especially in 2.6.32 and .33) Since the turbo boost
issues are predominant on mobile platforms and mobile platforms have a
battery, I thought it to be appropriate to include this link which will
give your ext4 a "kick in the pants".  http://blog.loxal.net/2009/04
/tuning-ext4-for-performance-with.html  I know this link was made for
solid state discs (SSD's), but they work extremely well for conventional
HDD's as well.  Instead of a commit time of 100, I personally use 30.
Default value is 5.  I also applied some other tweaks in my
/etc/fstab... (included).
