    We found that when we upgraded from the VMS 3.7 AME to the VMS 4.0 AME
    that we did not run into problems with the calls to the executive.  We
    were able to continue running the IAS TKB.  Most, if not all, AME images
    run 5-20 times slower under VMS 4.0 AME.  It was sufficiently worse that
    it did result in the transformation of many things to native mode.  It
    even resulted in the upgrading of several PDP's to VAXes.  I have no
    benchmark on the second version of the AME.

The first version of the new RSX AME - V1.0, or did they start it out at
V2.0? - had severe performance problems, mainly in the I/O system.  (This had
to do with the way RSX device names were translated back and forth to VMS
device names; the AME ended up doing many, many logical name translations.)
I believe this may even have been discussed in the release notes - though it
could have been in the release notes for the "next" version, when the problem
was fixed.  Make sure you have a current version of the product....
