:ted Can you please take a look over this Windows build time regression? It happens on both 32 and 64 bit architectures. Since January 2nd, build times on this platform got obviously up. I noticed multiple Build Config changes which are related to Rust toolchain updates.

I need a second pair of eyes over this alerts also [1], as I'm not sure if they are related to this bug or not. [1] https://treeherder.mozilla.org/perf.html#/alerts?id=11068

Is it possible we're having infra changes, that aren't visible from in-tree updates?

I thought this was just rusttest builds, but the regression shows up in regular win32 builds as well: https://treeherder.mozilla.org/perf.html#/graphs?series=autoland,1625065,1,2&series=autoland,1460334,1,2

FYI Since January 12, this regression lowered down half-way. I'm pretty sure this is from infrastructure changes like those we talked about in bug 1429319 and bug 1429311. Still, it's clear that some configs from our side caused some regressions.

Since March ~10, build times have improved by *a lot*. Closing this as WORKSFORME.
