[mpich-discuss] mpiexec (MPICH2) launch too slow on Windows10.

My OS: windows10 mpich2: 1.3-32bit and 1.5-64bit I install both versions successfully, and I test the MPIEXEC -N 10 CPI.EXE example. It works, but with a very slow launching duration of about 4 minutes. How can I fix this problem? Thanks for any help! ZHIJUN
