[rt-users] rt-shredder - quicker method?

[Ruslan Zakirov]

I'm pretty sure you have a slow query in the log of slow queries.

It happens on mysql when version of the server is older than 5.0.45,
cuz a query RT runs to build owners may slowdown because of mysql's
optimizer bug. Even on 5.0.45+ some indexes changes may be required to
improve situation.

If you're not eperienced in optimizing mysql then you can drop indexes
on CachedGroupMembers table that starts from MemberId column.
