I'd have to look through all testing docs for the period but I remember
that we tested NTPL with 4.0 and found it hurt our performance.
Similar work-load: webservers, reading from slaves, writing only to the
replication-master, PHP
Maybe different sizing? We have a very large database spanning well over
35Gb now, with some extremely large tables in it. Most dbservers are
IO-bound not CPU-bound.
Are you using persistent connections btw ?
IIRC it was around Mysql 4.0.11 or so. You might have something in the
db size. Most of our database were on the small side... in fact I don't
think we had any servers where the databases for all the customers
didn't fit totally into RAM of a 4GB box.
Yes it was persistent connections.
