Snapshot tests run much slower on Xcode Cloud (Intel) compared to local Apple Silicon

[RobertAdamczyk]

Hi!

We’ve noticed a big difference in snapshot test performance between local runs and Xcode Cloud:
• Locally (Apple Silicon, M1/M2): each test finishes in < 1s
• On Xcode Cloud (Intel): the same tests take on average 4–6s per test

With a few hundred tests this becomes quite painful.

Has anyone else experienced this slowdown when running on Xcode Cloud’s Intel machines?
Did you find any workarounds or configuration changes that helped?
