When running Jest tests with concurrent execution enabled, latency spikes occur under high concurrency. The issue is observed when multiple test files are executed simultaneously, leading to increased test execution times and inconsistent performance. The problem appears to be related to resource contention, such as CPU, memory, or I/O bottlenecks, which bec
jestRSpec profiler top-N output and slow threshold configuration
RSpec's built-in profiler reports the N slowest examples and example groups after a run when enabled via --profile or config.profile_examples. The output includes location, description and elapsed wall-clock time per example, with timing that covers before/after hooks and let/subject evaluation. The goal is to use profiling to identify bottlenecks before opt
