object numWorkers extends GlobalFlag[Int]

Flag for defining the number of worker threads used by the Finagle Netty 4 backend. This defaults to 2 x available CPUs but this behavior can be overridden via the auto offloading flag.

{{ -com.twitter.finagle.offload.auto=true }}

When auto offloading is enabled and no explicit c.t.f.netty.numWorkers is provided, the number of Netty workers defaults to 1/3 of available CPUs with a floor of 4 (on a host with less than 12 CPUs, 4 Netty workers would be allocated).

Note

For the default value, we set a floor of 8 workers so in the case of constrained environments we don't end up with detrimentally small worker pool sizes.
