Max number of concurrent HttpWebRequests
I have an application (C#/.NET 4.0) which is consuming a WSDL service which is prohibitively slow, and I need to send requests in large quantities.
I am parallellizing the operation by creating several Threads to manage the requests. However, I'm running into the maximum 2 persistent HTTP connections allowed: if I run two threads, they both come back with 400ms turnarounds. If I run four threads, they all come back with 800ms turnarounds because they're being serialized through only two connections.
Interestingly, if I spawn several instances of the same proof-of-concept application, running two threads each, they all run with 400ms turnaround per thread; thus, the connection is per-instance rather than per-machine or -NIC.
How can I increase the number of persistent connections that my application will use?
(In case this is a vital detail, it's running over HTTPS)
Answer for when it's closed: It's a web/app.config setting.
<configuration>
<system.net>
<connectionManagement>
<add address="*" maxconnection="800"/>
</connectionManagement>
</system.net>
</configuration>
