the numbers, measured.
Real-world performance data comparing GitHub Actions runners across CPU speed, cache throughput, disk I/O, and AWS instance types. No marketing math — just the runs.
CPU speed & queue times
Which runner is fastest? Compare single-thread CPU scores, queue-to-start latency, and $/min across 7 providers on x64 and arm64.
Cache throughput
How fast is actions/cache on each provider? Save & restore benchmarks for a 4GB payload across transparent and provider-specific backends.
Disk I/O performance
Sequential and random read/write benchmarks. See how NVMe local storage compares to network-attached EBS across providers.
AWS EC2 instance shootout
CPU scores, on-demand & spot pricing, and interruption rates for every EC2 family. Find the fastest instance for your workflows.
