Hi, I found a performance loss of mpir 2.4.0 compared to gmp 4.3.2. when running gmp bench 0.2 gcd examples on a Core 2 Duo T6400, 2Ghz, 4GB Ram Notebook with Ubuntu 11.04, 2.6.38-11-generic-pae i686, gcc 4.5.2. The timings with mpir are: q@ubuntu:~/gcdtrunk/trunk/ix86-Linux$ ./gcdtest 10000 5000 Calibrating CPU speed...done Multiplying 10000-bit number with 5000-bit number 27235 times...done! RESULT: 2749 operations per second q@ubuntu:~/gcdtrunk/trunk/ix86-Linux$ ./gcdtest 100000 50000 Calibrating CPU speed...done Multiplying 100000-bit number with 50000-bit number 656 times...done! RESULT: 66.0 operations per second with gmp: q@ubuntu:~$ ./gcdtest 10000 5000 Calibrating CPU speed...done Multiplying 10000-bit number with 5000-bit number 32406 times...done! RESULT: 3239 operations per second q@ubuntu:~$ ./gcdtest 100000 50000 Calibrating CPU speed...done Multiplying 100000-bit number with 50000-bit number 817 times...done! RESULT: 81.9 operations per second That's very sad because I'm working as a Singular developer and we may want to switch from gmp to mpir but this performance loss seems to slow down our tests.
