# Threads

The maximum number of parallel listening threads for index actions.

Set this parameter to the number of index actions that the server can receive at the same time. IDOL queues these actions, and processes the queue using a single processing thread.

You can calculate the optimum number of threads as follows:

(1 x Num CPU's) + 1 spare thread.

The optimum number of threads also depends on the number of clients sending index actions to IDOL. For example, if you have only one CFS sending index actions to IDOL, you need only one thread.
