Hi Everyone,
I'm having some issues with my recently upgraded WPMU internal blog engine. I upgraded from 1.5.1 to 2.6 yesterday and everything seems to have gone fine. No real issues except that it's running dog slow. And I mean really slow.
The server is set up as it was for 1.5.1 and I kept all the files that were required. None of the plugins are currently enabled and I've removed the MU plugins temporarily to try and figure out where the issue lies. Has anyone else had this problem and what areas would you all suggest to look at first.
There are no errors coming up in the php log, the database is being written to, there is virtually 0 load on the CPU and memory usage is well below what the system is capable of. We've also tried changing to a number of different themes in case it was UI related, but even the admin side of things is slow which suggests to me that it's not UI... but back end somewhere...
Any suggestions would be really useful.
