| - | 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 both natively, and for the CloudLinux/Apache-specific implementation of the PHP processor. This will improve the performance of LiteSpeed for transactions which are commonly used, and reduce the memory overhead on the server. | + | 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.
