In our SAS environment, SAS Stored process server has 9 multibridge connection. Maximum cost=500
session cost=1, context cost =100, cost per client=1
Hence according to theory, 4 requests can execute on one multibridge connection simultaneously.
So total of (9*4=36) requests should execute in parallel on the SAS Stored process server.
But when I open 12 tabs in a browser and hit one SAS stored process URL at the same time(with a very time gap of miliiseconds), what i observe is that, only 6 requests get executed at a time. and when 6 request completes its execution then next 6 requests gets executed.
In the STP log, it is observed that all 12 requests are being submitted only on 6 multibridge connections port.
So my question is, why not all 12 request to SAS Stored process from a single user are not executed at the same time on SAS STP server?
