Subject: [PATCH] Improve Server Thread Pool and Thread Priorities
|
|
|
|
Use a simple executor since Fork join is a much more complex pool
|
|
type and we are not using its capabilities.
|
|
|
|
Set thread priorities so main thread has above normal priority over
|
|
server threads
|
|
|
|
Allow usage of a single thread executor by not using ForkJoin so single core CPU's.
