| - | Checkpoint/Restore In Userspace, or CRIU, is an open source project which dumps all of the information of a running process to disk and restores it at the point of the dump. The LiteSpeed Enterprise Edition Web Server now supports CRIU for the CloudLinux implementation of the PHP processor. However, generally, we don't recommend you enable CRIU unless you have any special need since CRIU will use much more server resources while no performance benefits. | + | **IMPORTANT!! CRIU may cause stability issues! Enable CRIU AT YOUR OWN RISK!** |
