Hi weiyen, I get EXACTLY the same thing. Perfomance is great (like previous installations I’ve done) and then I make a post and it grinds to a holt.
This isnt with a hosting company, this is on a fresh install of Fedora7 on a dual Opteron 2212 4GB Ram, Mirrored SAS Seagate Cheetahs, so the machine isnt the bottleneck!
Its a fresh copy of WordPress with no plugins, does it on any theme (and inside the admin) and I’d tried switching back to previous versions of wordpress which made no difference.
CPU, ram and network useage are very low, it just seems to wait and think about anything for 20 seconds before sending back any data.
Any Ideas?
