My site has been suffering from slow delivery lately and I’m not really sure of the cause, but I have been wondering whether one of the WP plugins that converts a site to static pages might be worth trying. Alternatively, I currently do not have caching enabled. Would that help, and is there a recommended plugin?
Object caching is definitely the way to go. Another option is to ask your host if they recommend something that works particularly well with their setup.
Re: Caching -
WP Super Cache is another option. Might need a tiny bit of persuasion for the current version, but in theory, all “older” versions work perfectly well, too.
Tiny bit of persuasion means: The developers added a “Requires WP 6.7 or higher”, but thats just not true, underneath its almost identical to older versions, so editing that part in the Readme file / plugin file fixes the issue of “cannot be installed” / activated.
Also, as an additional measurement: Autoptimize. Caches assets, ie. CSS + JS files, and allows for more optimization like Above-the-Fold CSS, inline CSS / JS aggregation (only for advanced users), etc.
I wont offer any suggestions for statification, because I havent used any of these plugins in a while, and I dont know how well or even IF they work with ClassicPress at all.
Thanks for the other recommendations. Popping back in here to say that @mwaters suggestion seems to be working very well for me. I’m not sure how to interpret all the statistics, but I do know that pages I have not looked at in a long time are served much faster now.
