I am redoing mine so that I boot from a different drive and just test on one large RAID5 partition so that the layout is as consistent as possible
I/O (reads, writes at fairly large multiples of the sector size -- 512k is a good number) and small I/O size (512 bytes is good). This will help identify the source along two dimmensions: are we looking at a basic storage I/O problem that's present even without the file system, or can we conclude that some of the additional extra cost is in the file system code or the hand off to it. Also, with the large and small I/O size, we can perhaps draw some conclusions about to what extent the source is a per-transaction overhead.
Apart from postmark and iozone (directly to disk and over nfs), are there any particular tests you would like to see done ?
Also, anyone know of a decent benchmark to run on windows ? I want to test samba's performance on the 2 platforms as seen from a couple of Windows clients.
