Jeff, could we please have P4-optimized binaries of GMP-ECM?

If you are talking about MSVC 32bit versions, that is what the 32bit built is made for, the Pentium 4. But as we have seen here it might be faster to roll your own Linux/cygwin version.

There are no 64bit Pentium4 versions.

Can you please compile ecm 6.2.3 with GMP 4.3.0 for Core2 Win32 ?
It will be interesting to see the speedup from GMP 4.3.0

Is that aimed at me? I can give you cygwin benchmarks with GMP 4.3.0 but can't compare GMP 4.3.0 with MSVC builds because GMP 4.3.0 has no Windows compiler support.

what about mingw?
can't you cross compile stuff for windows with that?

Here are some more binaries for gmp-ecm 6.2.3 + gmp 4.3.0:

Linux, 64bit, Core2: ecm623_lin64.tar.gz
Linux, 32bit, Pentium4: ecm623_lin32.tar.gz
Windows, 32bit, Core2: ecm623_win32.zip

What command lines did you use for configure to compile gmp-ecm and gmp 4.3.0for Win32?

Thanks,
Jeff.

You can create a 32bit binary that will run on Windows with mingw yes, I was just pointing out that GMP 4.3.0 does not have Windows support so can't be used by the Visual Studio compiler, you need something like gcc (ie: in cygwin or mingw) to compile the Linux version of the source.
