Remove hyperthreading multiplier to improve performance.
Tests on my local machine show that the Hyperthreading multiplier is significantly hurting our builds times. Running with 8 logical cores is 11% faster than running with 4.8 cores when doing builds on my Mac.
macOS 10.12
MacBookPro 2017 (1 CPU, 4 core, 8 hyperthreaded)
1434.259 with --jobs = 5
1274.459 with --jobs = 8
I'll do some similar tests on Linux to see if it makes sense there.
