What would you suggest? fio? bonnie++? If you are aware of any benchmarks that illustrate cache performance specifically, I can try them out.

Another problem that I see, which looks more serious, is that the SCSI subsystem has turned off write cache for the hdd, I have no idea why. I tried using the older Adaptec SCSI driver in the kernel but it made no difference.
