There is some kind of interaction with the underlying machine (see
comment 104 in said bug, where the binaries perform identically on a
local machine, but differently on infrastructure), but we haven't
tracked that down yet.
From comment 104 it seems that it is possible to reproduce the slowdown from
the unstripped cross builds locally. Has anyone profiled one of these
builds comparing them to an unstripped non-cross build to see where the
additional time is being spent? I couldn't tell from the bug if this
investigation has happened.
My understanding is that the slowdown cannot be reproduced on local
developer machines, but can be reproduced on loaner machines from
infra.
Huh. That's interesting and even more puzzling...
I don't think anybody has tried profiling on infra to see
where time differences are.
That seems like the obvious next step to investigate to me. We should
*really* only talk about stripping builds as the last resort IMO, since
we have way too many developers using OSX every day...
