Slow disk I/O - was Re: Seeking Help

[geoff at thebakershome.net]

I do not know for sure. I get good benchmark sppeds in 12.10 as well. The
problem is when dealing with lots of small files (apt-get update,
compiling many files, etc).

I do not know how to properly test this from the live 12.04 disk.

I moved some data around on the hard drives overnight. Tonight I plan to
install 12.04 onto one of the platter drives. This should allow me to to a
proper test of the same commands (apt-get update) and better compare the
performance.
