[Yellow Slider]

It's killing me, I have 2 boards on my server one has a DB which weights 320 MB
the other one is 800~ MB, and im using memcache (and there isn't any improvement in the page generation time)
- first board - On index Executed 9 queries (0.1.. s')
inside a forum Executed 13 queries (0.2)
inside a thread Executed 9 queries(0.2)
DB 300 MB ( 1 modification installed )

- second board (3.6.7)
on index - Queries Executed 9 (0.66 s')
in a forum - Executed 14 (1.6 s' DAMT!!)
in a thread Queries Executed 24 (0.9 s') (24 que' What The Hell?!)
DB 800 MB (highly modified) - running memcache and it hadn't helped at all..
how can i decrease the page generation time?

i run debug mode, and i don't really know how to read this tool output..

I have to do somthing..

Thanks lot..
