Servers
Performance and autotune
Settings for nginx, PHP-FPM, OPcache, the database, Valkey and the kernel computed from your server's hardware.
Performance shows the profile Zefily sees — CPU cores, memory, disk, PHP workers, PHP sites and services — and tunes the server for it.
Autotune
Autotune computes nginx, PHP-FPM, OPcache, database, Valkey and kernel settings from the server's hardware and the services that run on it.
- Compute plan lists every change: file, setting, current and new value.
- Apply writes them. Every file is validated first, services are reloaded and health-checked, and everything is rolled back automatically if a check fails.
- Roll back returns to the settings before the last apply.
Automatic tuning
With Automatic tuning on, Zefily recomputes and applies the tuning when the web stack is installed and whenever a site is added or removed, with the same checks and automatic rollback.
Per-site limits
Autotune sizes the shared pools. Each PHP site's own memory limit, upload size, execution time and other php.ini values are on its PHP pane — see PHP settings. Page and object caching are per site too — see Access, caching and protection.
