Is a bigger runner always worth it?

What doubling the vCPU did to each build, on each provider's own runner line: each step usually saves less time and costs more per build.

Median across providers: from 4 to 8 vCPU, each build ran 28–32% faster for 35–44% more per build; from 2 to 4 vCPU, 37–46% faster, cost per build +8% to +20%.

Median across providers: from 4 to 8 vCPU, each build ran 28–32% faster for 35–44% more per build; from 2 to 4 vCPU, 37–46% faster, cost per build +8% to +23%.

Median across providers: from 4 to 8 vCPU, each build ran 28–31% faster for 37–40% more per build; from 2 to 4 vCPU, 38–53% faster, cost per build −24% to +20%.

Median across providers: from 4 to 8 vCPU, each build ran 28–31% faster for 37–45% more per build; from 2 to 4 vCPU, 38–53% faster, cost per build −24% to +21%.

  • Each line is one provider's runner at 2, 4 and 8 vCPU, its vCPU count in each dot (hollow: under 3 runs so far); RunsOn's is the bold one (m8a / m9g, not its fastest or cheapest).
  • Right costs more per build, lower is faster: the shaded corner, bottom left, is where you want to be.
  • Dashed lines join equal time × cost. A step that drops more steeply than them bought time cheaply; one that runs flatter mostly bought cost.

  • Disk Small random reads (QD1) on x64: Blacksmith 8 vCPU leads with 81,150 per second, 46× the slowest disk (AWS CodeBuild, 1,766). That is a disk's limit, and a build often never reaches it.
  • EC2 storage NVMe, gp3 and tmpfs on the same instances, and what each does to the builds above.
  • tmpfs The workspace in RAM instead of on a disk: what it does to the builds above, what it costs and where it does nothing.

Head-to-head

Two runners of the same size, build for build. Cost per build decides: a faster runner that costs twice as much per build is not the better runner.

Cost per build is variable cost only; licenses and plan fees are flat, on each provider's page. Estimate your bill
