Yes. I downloaded 1.2.9, 1.3, and 1.3.1, all within minutes of each
other. All are configured with --enable-static --disable-shared.
Each is installed in its own directory under /usr/local and
I use full patch names to mpicc and mpiexec.
I just rebuilt 1.3.1 without --enable-static --disable-shared.
There is no change in performance. 1.3.1 is a factor of 10
slower than 1.2.9 with messages of ~10KB and smaller.
I've used svn to grab trunk. Once I determine how to build
the trunk, I'll do a binary search to see if I can identify
the revision where the problem first occurs.
