Update worker threads to better optimize gate memory
This change updates our worker section so that we're not spawning so may
worker threads in the AIO. This simple change allows us to save quite a
bit of memory which is extremely important when running in an resource
constrained environment.
Example Before:
total used free shared buff/cache available
Mem: 15G 8.3G 295M 422M 7.1G 6.5G
Swap: 1.0G 14M 1.0G
Example After:
total used free shared buff/cache available
Mem: 15G 5.6G 4.4G 458M 5.7G 9.1G
Swap: 1.0G 13M 1.0G
