It seems that 1.2 is slower than 1.1 was on my K8 system. Neither was tuned so maybe the default parameters are worse off now for my system? Testing all base 2 pseudoprimes from 10^15 to 10^16 with BPSW took: MPIR 1.1.1. = 1m26.068s MPIR 1.2 = 1m32.788s GMP 4.3.1 = 1m34.058s I guess I could try tuning and see if that helps.
