What type of SCSI controller are you using, was performance always very slow or has it just started recently, there isn't a lot of information in your message but it sounds a lot like a hardware issue to me though it could also be misconfiguration. Check /var/log and see if there are any error messages that explain it, are you certain you aren't experiencing failing hardware? Also is CPU utilization abnormally high, try running some disk benchmark utilities or otherwise measure I/O performance. Are you running a custom kernel, if so does it perform differently with the GENERIC kernel? There are any number of things on the hardware or software side that can manifest as performance problems.
