Re: Speeding up XFS

Haven't tried 64 and 128 yet, but 256 made ugly ascii error messages on my
screen (generic mount failed message).  I'd increased the #buffs to 8 and
the bufsize to 262144, and got failures on mounting.  #buffs=8 worked though
and that alone seemed to improve "rm" speed noticably.  It's on my 
"todo"l list
to try 128 and 64.  My memory might be too fragmented, dunno -- 
computer's memory
too...:-).  This was under 2.6.5 kernel.  I wouldn't put too much weight 
on the problem
until I've done some more testing to narrow it down, but thought I'd 
mention it as a data
point.  System I tried it on had been up for 15 days...

Total mem=1G with 128M in high mem.

-l

(musing: I wonder if we will need DOS-style disk defragmenters for 
memory  for
systems with long uptimes and large memory...) :-)
