I use jkdefrag also. I can't vouch for current improvements, but several years ago I improved the performance of an application for a client of mine from 3 sec. to 1 sec. response time with a defrag. This was with an older, client-heavy Powerbuilder app. jkdefrag just runs in the background - I figure it can't hurt.
