This would be interesting to know, doubtless, but please note that MySQL 4.0 is either no longer supported or will reach that status in the immediate future. It would be more interesting to see what the performance difference is between Linux and FreeBSD with MySQL 5.0, which has just been released. If you find reasons to believe that any problems you're seeing are a MySQL problem, please let me know. Greg -- See complete headers for address and phone numbers
