-As such there is no hard limit in N99panel w.r.t. number of websites/vhosts you can have. Practically it is based on the resources such as RAM and CPU, RAM is the more critical factor and below we would explain the same.

It may consume more RAM if more libraries are compiled/integrated into the PHP process or based on programming logic, the RAM consumption can vary greatly. Also the PHP-FPM process lifecycle also has a role to play in it.\\

If Varnish is enabled for a WordPress website under N99panel, it help reduce the number of PHP processes based on certain scenarios.\\

 So now if our system has 2 GB RAM, going by above estimates, should be able to handle about 12-13 concurrent PHP processes. Any processes more than that can lead to slow response or un-responsive system or OOM (out of memory) issues like killing of a process.
