Hi. We are having this issue that every request on the admin area takes around 4 mins to complete. Frontend loads fast so no issues there.
We already tried truncating log tables and turning off Mage_AdminNotification, no improvements seen.
Enabled profiler and got this: (sorted by time, descending)
Any recommendations how to fix this? Thanks!
Unfortunately, the picture didn't come through. Is it the entire admin? or specific pages in the admin?
I've seen issues with admin pages running extensions, like Extended Grid extensions, that can easily get slowed down to a crawl.
Check that your admin session size is not being exceeded:
Try increasing it if you see session errors in system.log
