multiple threads on a single disk will likely results in significantly slower searching, possibly an order of magnitude or more slowdown depending on many factors such as available RAM, etc.

Would multi-threads on a single disk produces any performance advantage? since i don't see CPU is utilised 100% normally. In this case, does the bottleneck happens on the mutli-thread concurrent process sharing or on the single disk read? if its the latter, probably, I can get away by putting multiple indexes on seperate hard disks, but still runs on single CPU. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
