commit 6f87c7d567c9006b139b01fd1ab3bb9420fb407d Author: Erno Kuvaja <[email protected]> Date: Mon Feb 12 16:58:03 2018 +0000 Limit default workers to 8 With modern servers it's not uncommon to see environments that has dozens of logical processors. Glance defaults workers to number of these logical processors seen by OS and each worker spins up pool of 1000 threads. Having dozens of these thread pools consuming resources is total overkill for most of the environments. This change limits the amount of workers used by default to 8 which should be plenty for most of the deployments. This limitation does not affect if more workers is specifically configured in the config file.

Maybe we should consider limiting the total number of workers unless sepcifically configured by deployer.
