2186.0. "How many threads does DCE use behind the scenes?" by OZROCK::GILLESPIE () Wed Mar 12 1997 01:00

Our customer, Optus Communications, wants to know a formula
to predict the number of threads to expect per process.
The application is single-threaded but uses DCE for
security, and CDS for a repository.

The customer says that he observes about 8 threqads per
application process. He needs to know the upper limits of
this for his scalability planning.

Since DCE components call each other frequently, some procedures create
threads as a side-effect.  In general, your first CDS or security API
call will initialize several threads in RPC, and CDS will create several
as well (not sure about security).  So, 8 threads is very reasonable
once you are running.  Since the application is single-threaded,
additional CDS threads are unlikely.  For planning purposes, 10 would
be fine, unless you want a larger fudge factor.
