I've set up a site for a friend & having problems with the loading speed of the pages.
Once clicked on the site, the header & the left sidebar load instantaneously but the centre & right sidebar take ages to load (using Firefox). With IE6, it's the whole page.
After clicking on any link in the page bar, again, it takes a long time to load.
I've tried installing different plug-ins - WP Widget Cache, wp-cache & WP Super Cache but this makes no difference.
