Edge server workqueue does not fully utilize max number of threads #357
The number of threads used by the workqueue (WQ) is adjusted dynamically, based on the number of queued requests. Adding more threads happens by doubling the number up to a configurable maximum. Threads are removed again after a while if the number of queued requests is low.
This might lead to less threads being used than configured, e.g. the following was observed:
max number of threads: 16
first burst -> WQ scales up to 16 threads
idle period, some threads are taken out of service (at the beginning of the next burst)
