Re: MIPS kernel snapshot testing

bonnie++ might be a good start.

Cheers for that, I've enabled it now. Haven't used SCSI in a long time.
Here are attached the results of my testing, all on the same O2
machine. The files are:
bonnie.debian (Martin's latest snapshot on Debian Lenny)
bonnie.gentoo (Latest mips-git kernel they have on Gentoo)
bonnie.gentoo-live (Gentoo with the 2006 live CD kernel [2.6.17])
There was no way I could run bonnie on the Live CD as I couldn't
compile/emerge and the already compiled bonnie must have used a
different abi. So I just took out the live CD kernel and booted the
system from that instead.
A reminder: The live CD's hdparm claimed 61 MB/s cache reads but the
same kernel only claimed 29 MB/s on the installed system.
I hope these are useful.
Cheers,
Jimmy
