No.  We loaded up a new computer with Win7 and Java 7 and the software 
that had been running under Java 6 ran so slow that we couldn't use it. 
  The new computer was multi-core, more memory and faster but the Java 
code ran so slow we couldn't use it.  Then we install Java 8 and it is 
back to its old self.

Really strange.
