Has anyone noticed slow downs in Rspec test suite when upgrading from Ruby 3.4 to 4.0 ? Our test suits with 4.0 is 2x slower than 3.4 We have no changes beside the Ruby version to upgrade to 4.0

That’s very odd. I would have expected a significant speed up to be honest because RSpec allocates a lot of objects, especially when used with factorybot.
