Question: What must go wrong for a build to be 180x slower on a server than on a laptop?
- cs02rm0 10y agoUsing an EC2 t2.nano instance for a build server. When they're out of CPU credits it's game over.
- contingencies 10y agoMaybes: Packaging latency in archive formats (compress before upload, decompress after). Network latency on the upload/download. Block IO performance on the server. Virtualization overhead. Memory or processor constraints. Assumption of equivalence is spurious (eg. server is doing multi-architecture builds and full suites of tests including eg. regression tests). Yep, something like that.
