Hi All!
So I am hunting to find what happened.... Stay tuned (or help me :) My goal is to restore 2.5.4 speed for 2.6.1 !
I at least fixed some PHP issues: The bookmark querying in left frame, the nesting reducement and some collation string caching.
So this finally speeds up my left frame generation; now on to other "slow" places - do you suspect performance bottlenecks in PHP functions, or in HTML/JavaScript functions?
Regards, Garvin.
