Hi Greg and others, I was just about to raise the issue of performance regression from this change. If we are aiming this at the 49 release, I would like for us to improve the situation described in bug 1259923, a 15% performance regression across all Talos tests covering Windows platforms, which Joel brought to my attention yesterday. I don't think we can accept that if it means a large noticeable slowdown in performance for Windows users in the release population. (Even though we really, really want to improve the toolchain and build time for developers and our own infrastructure.)
Can we put some engineering resources into investigating the test results and mitigating the perf regression? 15% worse across all Windows tests should probably block the release. We don't have hard and fast criteria for what would be an acceptable perf hit. I think the platform (and probably product team) should discuss that.
