Hi,
We have made some comparaisons between NetBSD 0.9 and Linux, and it appears that
Linux's disk i/o calls are much faster in some case (time gives 4 seconds versus 4
minutes for a programs which make direct acces writing and reading on a file, on
exactly the same hardware).
It seems that Linux bufferize the file, as NetBSD always write it on the hard
disk.
Am i wrong ? Is there any way to change this ?
