[Haskell-cafe] Are type families really this slow, or is this a GHC bug?

I don't know much about type families, but I recall this: 

The bug is marked as fixed, but perhaps behaviour you observed shows that there are other cases 
where constraqint solver is slow. I'd consider reporting this as GHC bug.
