In case there are users using different languages in the GUI, the interface could load slower since the GUI needs to re-initialize different code parts (multisite plugins) each time a user with a different language accesses the GUI.
In technical detail: Each apache process has one Python interpreter which serves the Check_MK GUI. Once a request arrives, the whole GUI code is loaded in the language of the user. This loaded GUI is cached until a user with another language requests a page from this apache process. The cache needs to be renewed then. This takes a lot longer than simply using the cache.
We have now improved the situation by routing the requests to language dependent, so called, sub interpreters. Each apache process can now have a default language (english) interpreter and an e.g. German language sub interpreter which each have caches on their own and thus never need to reinitialze their cached GUI now.
