If we consider performance issues based on design, planning the BigInt architecture could be designed in two ways
1. 3 layers to allow optional binding to Boost's own bigint, GMP, or anyother bigint library, for the user during compile time.
2. 2 layers if we plan to limit Boost.Bigint's options to only itself and GMP.

IMO you should look at the discussion on a numeric_adaptor by Barend Gehrels and some draft code mentioned in http://archive.freebsd.se/?ml=freebsd-questions&a=2007-05&m=11343770 to get some idea of the problem and a plausible framework which might include 'BoostsOwnBigInt' as an alternative to GMP etc. Paul PS But you should also be aware that another xInt project is being discussed on this group. --- Paul A.
