It wasn't that configuring opcode caches is complicated or difficult.

It wasn't that configuring opcode caches is complicated or difficult. It's that they locked up every few days, no matter which one I used or how I configured them. At the point where I wrote a cron script to kill PHP every 24 hours, I realised the extra few percent weren't worth it. Maybe it's improved, but: four times bitten, twice shy. > Nginx stores the pages in RAM in a tree-like structure with pretty fast access times. On disk caching delegates this to the OS, which is pretty good at it. Badly behaved plugins and themes are not a solvable problem on Wordpress, because it's essentially a cooperative multitasking environment. One bad actor can hog all the resources and there's no way to constrain it. It seems as though very few plugin authors know what O-notation means (so many nested loops), what EXPLAIN QUERY is or that tinkering and and firing up a copy on your laptop isn't really testing.
