Installation go get -u go.uber.org/automaxprocs Quick Start Performance Data measured from Uber's internal load balancer. We ran the load balancer with 200% CPU quota (i.e., 2 cores): GOMAXPROCS RPS P50 (ms) P99.9 (ms) ------------------ --------- -------- ---------- 1 28,893.18 1.46 19.70 2 (equal to quota) 44,715.07 0.84 26.38 3 44,212.93 0.66 30.07 4 41,071.15 0.57 42.94 8 33,111.69 0.43 64.32 Default (24) 22,191.40 0.45 76.19 When GOMAXPROCS is increased above the CPU quota, we see P50 decrease slightly, but see significant increases to P99. We also see that the total RPS handled also decreases. When GOMAXPROCS is higher than the CPU quota allocated, we also saw significant throttling: Once GOMAXPROCS was reduced to match the CPU quota, we saw no CPU throttling. Development Status: Stable All APIs are finalized, and no breaking changes will be made in the 1.x series of releases.
