This was not at all my experience with DEC Ada on a VAX 11/785.  Typical
compilation times were in the range 600-1500 lpm depending on the complexity
and size of the code being compiled.  Perhaps somebody at your site didn't
set system parameters correctly and you ended up doing a lot of paging?
I love the DEC ACS environment; too bad it's not available under Ultrix.
