Re: Hard disk speed - Maybe OT

Hi Nikos

Okay thanks for that, something I didnt know!

I am mostly manipulating 80-100KByte files so I guess that qualifies as small.

I note there is disk elevator adjustment that I may look at. (ie wait for a list of read and writes to gather before making the heads move and do it)

OBTW already using a RAM disk for preprocessing.

Cheers Bob

Was considering playing with buffer flushing times or maybe the file system itself. It is running vanilla reiser.

I'm not an expert, but over the years the usual thing I read about Reiser vs ext3 is that Reiser is very fast with *small* files while ext3 is very fast and uses less CPU with *big* files.
