Subj:   Re: What would cause explains to slow down?
From:   Geoffrey Rommel

  My question is: Even when our system is busy usually an explain or help stats takes only a second or two....lately during peak times I have explains taking up to one minute and help stats that long or longer. What bottleneck would this represent?  

This sort of thing is usually caused by locks on the DBC tables, DBC.AccessRights in particular.

It is just possible that your system might need more PE's. (We have 104 on a 400-AMP system.)
