Performance issue

@runeksvendsen this looks bad, but hopefully easy to fix. Can you help with adding a minimal self-contained example that demonstrates the issue?

[sol]

I just did a couple of test with the example given in the tasty readme and couldn't see any performance difference between hspec and tasty.

What I noticed though is that for some reason ghci is about twice as fast as compiled (regardless of optimization level).

I will see if I can deduce a proper, minimal example.

Lessons so far: it's not shouldBe vs == (makes no difference if I switch out shouldBe with ==).

Possible clue: are Hspec and Tasty handling depth in the same way? In other words, does defaultConfig { configSmallCheckDepth = <depth> } for Hspec has the same effect as localOption (SC.SmallCheckDepth <depth>) for Tasty?
