Retain is multi-threaded and able to make use of multiple CPU cores. The base server uses 4 threads, and the Indexer starts with 3 threads. If more than 7 CPU cores are available, additional Indexer threads are spawned. The basic formula is [cores - 4 (minimum 3)].

HINT:Micro Focus Testing has determined that 8 CPU cores is optimal for performance gains, allowing Retain 4 threads and the Indexer 4 threads.
