I called GoDaddy again about the slow performance of the site, but they’ve confirmed that even with the upgrade it’s just swamped with user requests. Mirroring content wouldn’t even help, since it’s not a traffic thru-put problem.
The only real solution at this point would be to upgrade to my own server, which is $150 a month. And with donations still topping out at $0 a month, that’s not economically feasible. 😦
I’ll spend some time breaking up content so the individual pages have fewer images and see if that improves things.
