[pLog-svn] Process size

[Ayalon]

Nope, there's nobody who has so many post in the mainpage as I configure
everybody's blog.

It's not just an issue with all bots, it's only with yahoo bot. When
searching the net I found more similair problems. No check is done who is
coming on the site or something??

I guess it's the same issue we had in devel.lifetype.net.

One thing you should check is whether you've got any user who has configured
his/her blog to display something like 80 or 100 posts in the front page, as
that can cause performance problems. There's already a fix for that in LT
1.2, but in the meantime you will have to keep an eye on it on your own.
Otherwise a crawler performs the exact same operations as a user via a
browser would do.
