I ran a benchmark and got 16500 evaluations per second with standard
gnubg, but only 10500 with the 2.6 build.

I got similar numbers:

msdev gtk 1.3 command line or gui 20,000
2.6 gui 15,500 and (2.6) command line 20,000

Looking at the calibrate function I see that it calls a callback every
couple of hundred evals.  If you add the following 2 test lines (marked
with a +) to speed.c you can check if it's your build options or gtk 2.6
causing the problem (as the figures should then be identical to the
command line version).

+ fX = 0
        if( ( c0 = clock() ) < 0 ) {

+ fX = 1
        c += c1 - c0;
