Please clarify - your subject line says the EM is taking a long time, but the 
content here suggests the post-EM simulation process is the problem.  Which is 
it?  Are you sure the .mdp files were identical?  Small changes can have big 
effects on performance.  Are you sure the hardware is fully functional?  A stuck 
node or lagging file system can explain slow runs.  If mdrun is still churning 
along without crashing, most likely the problem is external.
