WordPress Site Health had been nagging me to use a persistent object cache. I already run Zend OpCache, so I wondered what else I needed.

OpCache is an opcode cache: it stores the compiled bytecode of the PHP source so the engine need not recompile it on every request. The object cache is a different layer, holding the results of database queries and transients. WordPress ships with a non-persistent object cache that lives only for the duration of a single request; making it persistent means backing it with something that survives across requests, such as Redis.

On this site I manage the WordPress tree with svn and do not let PHP write into it, which changes a couple of the steps from the usual click-in-the-dashboard instructions. While I also generally prefer nginx and PHP-FPM, this site is still on Apache with mod_php. However, the installation is basically the same regardless of the web server software, but troubleshooting differs between them. I’m covering both here. (more…)

Thank you to everyone in the NetBSD community whose posts kept the planet spinning all these years, and thank you to Venus — and Sam Ruby before it — for making the aggregator possible in the first place. Now we must say goodbye to things Python 2.7.
