Blog hosting upgrade

I just upgraded my hosting plan, and we’ll see if that solves issues with the site performance. In addition to everything I mentioned in my last post, I also took some additional steps to improve performance, captured here for the sake of anyone else who has issues.
- I fired off an email to the maker of Category Icons, which seems to be one of the common slow queries. For a while today I had it disabled outright, but I seem to have more headroom on this new hosting plan, so the icons are back.
- I found that wp-cron.php, which is what the blog uses for scheduling posts and other cleanup tasks, was generating a lot of hits — as in, a quarter million this month alone, far outweighing most of the blog traffic! This appears to be a common problem. I followed the advice found here on how to disable WordPress’ built-in cron stuff and instead use a regular cron job. We’ll see how that does and whether everything works more or less like before.
