[Quantlib-dev] Performance hit of QL_REQUIRE

[Francois B. <ig...@gm...>]

Hi,

It seems since v1.0.0 a lot of QL_REQUIRE statements were added. Do you
have any idea of how that impacted on the performance, if any?

A user of the QLNet version noticed a big impact, but in QLNet we use a
normal function, and not a macro, so the impact is somewhat expected
(parameter values are evaluated whether or not the condition holds).

I'm curious as to whether any impact was noticed in QuantLib.

See discussion at https://github.com/amaggiulli/qlnet/issues/40

thanks
