I’ve just made a big change to the blog’s configuration. In theory this should not be noticeable to anyone (except that the blog will be down less frequently).
If, however, you notice anything different — faster or slower response time, for example — please post a comment letting me know.
For those who may care, what I’ve done is switched from PHP 5.2x with fastCGI to plain vanilla PHP 5.3. Supposedly using fastCGI speeds up WordPress, allowing more pages to be served at once, but I have come to think at least on a Dreamhost VPS it may be the source of random episodes of the server running out of memory. My plan is to run without it for a few days, and then start setting my cache back to more aggressive settings than the very limited ones now in use.
