Allocating additional server lockd daemons

Allocating additional server lockd daemons

By default, lockd allocates two kernel-based server processes, one for TCP and one for UDP, that handle lock requests from clients. You may allocate any number of lockd daemons for either transport protocol by using the -t and -u flags when you invoke lockd on the server host:

/etc/lockd -t 3 -u 3

This will allocate three lockd daemons for lock requests transmitted via TCP and three daemons for those transmitted via UDP.

/etc/lockd 3

This will allocate three lockd daemons for handling UDP lock requests. This is desirable when you wish to process more lock requests or allow the lock requests to be processed faster.
