This topic was discussed more than one time by me too. A gentle person here even has written a patch for the GC to solve one of the performance problems I did find (I think such patch was never accepted, I don't know why).

I think D deserves a benchmark suite to test "everything". Haskell implementations have several of them.

Inside here you can find 3 tests of the GC (gc1, gc2 and gc3) (one of them is the binary tree test you already have seen many times):

Thy are tiny programs: I think a test suite has to contain both tiny and longhish programs, because the shorter ones are able to spot troubles in a more definite way, and the longer ones are able to spot less specific troubles.

(The gc1 benchmark is the one partially fixed by that GC patch).
