Re: Unstable speed or correct?

I'm not familiar with this program (BTW, you mean "palimpsest",
right?)

yep :-)

I would try running some other benchmark

iozone3 and bonnie?

Do u known other bench programs?

that can be run on
single-user

next day I'll try do these benchs to init 1

if it does, then I
would conclude that there's something wrong (possibly on your
hardware, like a failing disk doing retries/reseeks).

I already examined all disks by smartclt, hdparm and seem there aren't 
problems :-/

Is ram a possible problem?

How hardware test I'll do?

thanks :-)
