From: Sundeep KOKKONDA <[email protected]> Enabled the parallel-frontend-threads for faster compilation of rust code.
Test Results: A few tests ran by, with and without enabling this option. - Avg. default build time (w/o this option) - 56m 50.104s - Avg. build time with this option - 49m 17.224s - Performance Difference - 7m 32.880s faster builds (≈ 13.3%) Tests were performed by setting thread count as 8 & 16 but no much difference is seen. So, the parallel-frontend-threads = 8 is set.
