On my private wikt (1 user) and on the company wiki the ResourceLoader takes ~4-5 seconds to load on the initial loading.
This is only on the first load after no traffic for a while, then browsing around is fast.
- private wiki: MW 1.24.1, PHP 5.5.13 + Opcache
- company wiki: MW 1.19, PHP 5.? + APC
How can this be avoided?
