I have a query. On my local Windows 7 machine it takes 1.31 seconds to return the result. In the production database it takes 6 minutes and 15 seconds until it returns. The MySQL version on my local PC is 5.5.20 64-bit. In the production database the MySQL version is "mysql Ver 14.14 Distrib 5.1.55, for portbld-freebsd8.1 (amd64) using 5.2". That table is over 1.6 GB and over 26 million rows. Were using the InnoDB storage engine.
Have we exceeded some limit? Will deleting old rows in that table help? We don't want to loose old statistics unless we absolutely have to.
