hash-tables using equal? very inefficient ?

I re-wrote one of the hash tables I was using so that it was using
string=? instead of equal?

This made a big difference in performance.

I was using a pair as a key and it looks as though, from looking at
the code, that using an equal? hash is very expensive in terms of key
calculation _and_ cons'ing.

Does this make sense ?
