Nextcloud 23.02 OPcache interned strings buffer

[bb77]

Hi @MichaIng

Thanks for detailed the explenation.

Since more than 16 MiB are a bit unexpected to be ever used, if Nextcloud is the only web application served by your webserver/PHP instance, and the admin panel shows a recommendation to apply >16 MiB, it would be interesting to see your apps list. Probably we can find similarities or identify the app which allocates that much interned strings. Maybe there is indeed an issue with cache eviction in one of these apps, or it simply contains a large number of strings/text shown in its interfaces.

Ah ok. Does this mean the warning shows recommendations based on the actual usage of the cache? I asumed the test is just checking the values that are set in the configuration, and sometimes fails to do so.
