we have a painfully slow site at http://www.nofari.org. I replaced our photos with smaller version. I deactivated all the plug-ins and changed the theme to twenty eleven from weaver II. This didn’t make things better – the loading speed may be worse.
I took the time to update all the headers to fit the new theme size.
there are not many useful widgets available with this theme. there is a search box in the menu bar as well as in the right column. I think we only need one and I prefer it NOT be in the menu bar.
if you are more savvy you could try a caching and CDN plugin like “w3 Total cache” or “wp Super cache”. There are tutorials online but I would suggest against this unless you are technically savvy and have a bit of experience with websites in general and WordPress in particular.
other than that have you tried contacting your web server or checking their forum to see if their other clients are having trouble?
