Explanation:
The fw ctl multik stat and fw6ctl multik stat (multi-kernel statistics) commands show information for each kernel instance. The state and processing core number of each instance is displayed, along with:
The number of connections currently being handled.

The peak number of concurrent connections the instance has handled since its inception.

Synchronization works in two modes:
Full sync transfers all Security Gateway kernel table information from one cluster member to another. It is handled by the fwd daemon using an encrypted TCP connection.
Delta sync transfers changes in the kernel tables between cluster members. Delta sync is handled by the Security Gateway kernel using UDP multicast or broadcast on port 8116.
Full sync is used for initial transfers of state information, for many thousands of connections. If a cluster member is brought up after being down, it will perform full sync. After all members are synchronized, only updates are transferred via delta sync. Delta sync is quicker than full sync.
