What thread pool size should I use in MetaDefender Core v3?

A solid guideline and enforced maximum number of threads for MetaDefender Core v3 is as follows:

  • OPSWAT recommends 4 times the number of cores or just 20, which ever one is higher, but also less than 100, which can happen for example on a machine that has 32 cores.

  • The default value is 20, the maximum value is 400.

Note that less than 100 is for the initial starting point. The maximum value is still just 400.

For example, if your machine has 100 cores you may see improved performance with 200 threads.
