G2 very slow

I've an installation at this adress: http://tayfun.ilksen.net/album

It is working very slow. I've changed my host already but it is still slow. I've set my performance setting to Full Acceleration. I've uninstalled many modules. I've disable many future to show like Album Owner, Hits etc. It is loading about 20 seconds.

My host is Webhostingbuzz.

I can't use Gallery2 for this slow performance. What can i do?

Webhostingbuzz support is said that write this problem to gallery.menalto.com.
