Thank you for your response. I suspected that was the case and that the only bottle neck potential would be my mysql server.
Do you know if it possible to synchronize several mysql servers and then employ a load balancing solution?
I know it’s possible to do that with wordpress installations all using the same mysql server, but then the real bottle neck would be getting the data out of the single mysql database.
Also, I have been thinking of using WordPress MU to allow for our subscribers to have their own blogs within our site, so I’m curious if any solution proposed would also be supported through WordPress MU.
Thanks again for your response.
