OK. I'm frustrated now because I haven't heard back from the ISP folks about this. I wonder what else could be causing the trouble.
Just now, when in the dashboard area, I noticed that when I click on Dashboard itself, I get "Error in connecting to database." But everything else is working there, just slowly.
*EDIT* Well! I never did hear back from the ISP support guys, but I think I fixed it myself. I deactivated and deleted several plugins, including WP-Polls and Poll Daddy, and Next Gen gallery. I'm not sure which one was the problem, but now I'm getting normally fast loading time. Would somebody please test it yourself and let me know how it seems to you?

I am still getting the database error message when clicking on Dashboard from within Dashboard.
