Dropping this into triage for the team to look at.

In my testing it seems like glpABIGetStructTypeRangeOfField gets more expensive as the array gets larger and it gets called O(number of array elements) times.

NeedInfo - do we have anyone who wants to take a look at this?
Context: I recall Kelsey mentioned this slow compile bug is caused by Apple having a particularly slow implementation of glGetActiveUniformsiv, where other vendors have a caching implementation that answers quickly after the first call, so we should cache this ourselves across calls for the same program identifier. Entirely going by memory here, but that's what I remember.

Do we query the same information multiple times?
