in reply to bigint == horrible performance?

Yes, bigint operations are comparatively slow - don't use bigint if you don't need the extended precision.

See the "l, lib, try or only" and ensuing sections of the bigint docs for ways of getting vastly improved performance out of bigint on those occasions when you *do* need the extended precision.

Cheers,
