In the Services Controls tab, use the processor controls to configure the processing threads used to evaluate hits and sessions in the Canister.
For each Canister, there is rarely a need to increase the total count of hit and session processors above 8. Increasing the number of processors above this soft limit can have significant impacts on system performance and can cause spooling and potential data loss.
|Hit Processors||Number of processes to allocate for hit event evaluation in the Canister server. If the Decoupler Status is reporting spooling because of high unevaluated hits, increase the number of hit processors.|
|Session Processors||Number of processes to allocate for session archival in the Canister server. If the Decoupler Status is reporting spooling because of high sessions waiting for archival, increase the number of session processors. One of the primary functions of the session processor is to compress sessions for storage, which increases the rate at which sessions are ready for writing to disk.|
