    > Moving our workloads off GitHub Actions to third-party runners with faster CPUs, higher-performance storage, and better cache infrastructure gave us faster machines to run the same pipeline on

    Yeah, was not surprised to read this. Actions is convenient if you already use GitHub, but it can also be pretty slow. Given reliability is also a major issue with GitHub these days I expect to see more orgs moving to different pipelines

      I wonder why larger companies don't use self hosted github runners. You can buy a pretty beefy machine (TB of RAM, 256 cores, fast NVMe disk) and tests will run faster than on any hosted platform. Plus you don't have to shard as aggressively because more fits into one machine, benefit of shared page cache, shared persistent disk, can easily preserve working directory (for example my pnpm install takes 0 seconds, because the node_modules folder is already present from the previous run).

        Because they're running away from on-premise and the associated Ops teams.
