Just started looking at it, but in an initial set of benchmarks,
comparing one processor to one processor of the YMP-8, the EL was
running 5 to 8 times slower.  This is more than the difference in
clock rate would account for (each program was recompiled for each
machine).   We have not looked hard at the code to understand why the
differences; which will need to be done before any thing definitive
can be said.
