Ubicloud runner benchmark.
880 of 885 jobs finished across every suite, 5 failed (TypeScript 3, Cache 2).
- TypeScript is borderline at 8 GB or less: Ubicloud's standard ran out of memory, on some runs only; Blacksmith and Warpbuild never ran out; GitHub, Namespace and RunsOn ran out on some runs; AWS CodeBuild ran out too; 16 GB passes everywhere.
- Measured swap at 8 GB or less: Blacksmith 2 vCPU has 11 GiB, GitHub 2 vCPU 3 GiB, RunsOn 2 vCPU 7.6 GiB, Ubicloud 2 vCPU 4 GiB and Warpbuild 2 vCPU 4 GiB; AWS CodeBuild 4 vCPU and Namespace 2 vCPU have none.
