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...) :-)

Up to 256Kb log buffers on Linux should work now.
(i.e. 32K, 64K, 128K, 256K).
