Expose full OPcache settings in the dashboard
The dashboard currently only exposes OPcache memory size. But OPcache has two other limits that can silently cripple performance on multi-app servers: opcache.internedstringsbuffer and opcache.maxacceleratedfiles.
On my 8GB server with 13 WordPress apps, all sites suffered slow TTFB because the interned strings buffer (16MB) and file slot limit were exhausted, even after raising OPcache memory. Site Health showed opcachefull: true with a 67% hit rate instead of 99%. Nothing in the dashboard surfaced this, and fixing it required support tickets since these are PHPINI_SYSTEM settings that can't be set per app.
Requests:
Add internedstringsbuffer and maxacceleratedfiles fields next to the existing OPcache memory setting in Server Settings & Packages.
Ideally, show OPcache health (memory used, strings used, file slots used, hit rate) in server monitoring, so a full cache is visible before customers have to diagnose it themselves through WordPress Site Health.
These defaults are fine for 1-2 apps but break down on servers hosting many applications, which is a common Cloudways use case.
