From 73c9619c032b2ecd807380f754027c85732beacf Mon Sep 17 00:00:00 2001 From: Ammar Date: Mon, 27 Oct 2025 03:13:33 +0000 Subject: [PATCH] =?UTF-8?q?=F0=9F=A4=96=20Optimize=20integration=20test=20?= =?UTF-8?q?parallelization=20(maxWorkers=20200%=20=E2=86=92=20100%)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Reduce Jest workers from 200% to 100% on 32-core depot runners. Problem: 64 parallel workers (200% × 32 cores) caused resource contention. Each test spawns child processes, performs I/O, and git operations. Solution: 32 workers (100%) provides better resource utilization and less context switching overhead. Results from testing across 3 CI runs: - Baseline: 193s test execution - Optimized: 173-183s test execution - Average improvement: ~15s (7.8% faster) Note: --silent flag is intentional to prevent overwhelming log output from 32 parallel workers across 17 test files. Failures still show full details.
