How many concurrent *Ada* tasks has anyone out there in net.land
managed to have running simultaneously, with regards to performance
and on what hardware?

As a test case, we created and executed a program
which spawned more than 500 Ada tasks using the
Intermetrics Real-Time MVS Ada compiler on a 4341.  This compiler
uses one MVS task for each Ada task, and provides
for "true" concurrency on a multi-processor such as a 3090.
The primary performance problem involved certain
linear-list algorithms inherent in MVS dealing with
task creation.  Once the tasks were created, performance
was "fine."
