A while ago I came across a full-featured PHP application for controlling a daemon. It worked well with a small data set, but quickly became laggy with a dataset numbering in the thousands. Admittedly, it really wasn’t built for that kind of load, so I removed it and controlled the daemon manually, which wasn’t a big deal. Then a while later, I came across a post by someone who managed to mitigate the problem by shifting a particularly expensive operation to an external python program.
