Please upload the attached file to your admin/ directory and run it, and copy and paste the results. You should get something like this, only hopefully with much faster times:
Code:
Cache test 1...Done (341.828 msec)
Cache test 2...Done (304.107 msec)
Cache test 3...Done (304.835 msec)
Cache test 4...Done (314.325 msec)
Cache test 5...Done (304.61 msec)
Done with tests (617 users, 0.508818479566 msec per user)
The script loads all users and their ids into two arrays for cache purposes and I'm hoping that these obscene times are just my crappy computer. It's for a hack I'm making, or at least hoping to.
It runs five queries in case it matters.
