Are you sure to have used the proper layer of the library tuned to performance or have you used the casual layer tuned to coding facility ? What do you know of the Smalltalk big numbers library ? In which language is it written ? What are the algorithms used ? What were your benchmark programs ? What are your figures ? Be serious on such a topic please! Comparing arithmetic packages is not a trivial task and you cannot state ``Dolphin Samlltalk outperformed O'Caml by a factor of 4'' without strong arguments and evidence that this is indeed true.
