PHP-FPM service separation per webspace / cgroups integration
It would be very useful if ISPConfig would support one day PHP-FPM separation or with other words: every webspace in ISPConfig would have its own dedicated FPM daemon.
This would open up more possibilities like resource allocation through cgroups, or restarting the FPM service individually per customer.
It would also minimize the impact when a FPM daemon crashes. Instead that it crashes for everyone, a crash would only affect the assigned customer.
