I am going to create caches on some image services. It is said increase number of instances on the CachingTools can improve caching speed. I checked the instance number, it is set as 3. I guess it is the default.

My question is that what is the relation between the instances and the system resources. My server is quad-core (8 threads) CPU, 2processors. Am I right that each instance will consume one thread, and hold it until the caching completes?
