WordPress MU

I had my earlier installation that was fast also on the blogs, this was a 1.3.1 installation.

Now I have 1.3.3 installed, the blogs are sometimes very slow in loading and take forever.

At that same moment, the mainsite is very fast, never any problem.

I have checked DNS, RDNS, and serverload is so low, that's not the problem.

I want to figure out if this is a 1.3.3 issue or something else.

At the other side I think it might be Apache because sometimes the blogs are fast too, but not for long and they are laggy again.

Normally this is easy to solve and check, but I want to make sure not more people have this issue.

Solved :)

Minor DNS issue that should not have happened.. dunno why.

i also faced same problem and solved with restarting named and httpd. still i don't know WHY this happen, neither. (matsuatbct)
