(r2) BonnieResults - Tech

Bonnie is a simple filesystem benchmark which measures how fast it can read and write to a filesystem. These are results of bonnie runs that I've made on various machines.

Generic P133 64MB RAM, two HP 97560 (very old 5 1/4" full-height 1GB drives) on Adaptec ISA controller:

Single disk:

Running simultaneously on both disks, with a single file system on each one:

two-disk stripe on Adaptec 2940 PCI controller (with kernel compile on another disk). Compare this to the "8k stripe" result above.

Looks like the PCI controller is a win!

Something's not right - these numbers suck!

OK, managed to get dma enabled (don't know why I have to use hdparm) and now things look a little better:

I'm still surprised as hell that the VAIO smokes this machine in so many categories. I guess it does have a lot more CPU than this machine does, but I wouldn't expect that to matter for block I/O. Go figure.

UDMA comes up enabled by default with this drive; seems to use very little CPU. I think that something's wrong with the DMA support on the maxtor drive.
