[DUG-TO] Speed Optimization

[Design Guru]

Hey guys,

I really need help optimizing the speed of this site I built with Drupal 
6 - have tried tons of things to get it faster but am butting my head 
against the wall! http://juma.ca

Can you help me speed things up?  It seems like the speed is totally 
tied to database calls... I've got caching turned on for anon users and 
they're generally viewing the site quickly but for authenticated users 
speeds are erratic and at times take 1min to load a view/page?!!

Any recommendations of reads or people to help speed things up are 
recommended!

Thanks,

q./
