Yes, I do have that enabled.

But does it make sense that
normally I'll see something like "Generated in
0.01 seconds in which 0 seconds were spent on a total of 22 queries" but just periodically (some good days, some bad days) it'd take 10-20-30 or even close to a minute to load the page?
And if I wanted to test this, is there a way to "Mark All Read" for every member, and/or, if I uncheck the box will it clear all that info out of the database?
Thanks,
JG
