Life of a WCF Message webcast source code....

Last week I presented an MSDN webcast titled "The Lifetime of a WCF Message". As promised, the demo code shown is here: LifeOfAMessage.zip ( KB)

A couple of things to remember about the source:

It was built with the WinFx Feb CTP, but should upgrade to Beta 2 with no problem :)
Demos 1 and 2: set WCFReceiver101 and WCFSender101 as the startup projects
Demo 3: run the BindingElements project, then the MessageEncodings project
Demo 4: Set PerfTestSender and PerfTestReceiver as the startup project

I'm wondering why when I run your PerfTest its taking 20+ seconds for the Tcp binding. Your web cast was close to 5 seconds for the 10000 loops. Any thoughts on the results from my test. I have a 2.0 GHz dual core with 2 GIGs of ram.

10000 request/reply messages NetTcpBinding took 23.1129861 seconds

GCs: 17 Gen 0, 1 Gen 1, 0 Gen2

I even took off security to see if that was slowing things down.

((NetTcpBinding)binding).Security.Mode = SecurityMode.None;

I even tried adding named pipes and that was slower.

10000 request/reply messages NetNamedPipeBinding took 40.3099857 seconds

GCs: 17 Gen 0, 1 Gen 1, 0 Gen2

10000 request/reply messages BasicHttpBinding took 60.4190909 seconds

GCs: 91 Gen 0, 5 Gen 1, 0 Gen2

Worst still the Remoting code is much faster than WCF.

10000 remote object calls took 4.7378261 seconds

GCs: 32 Gen 0, 0 Gen 1, 0 Gen2

I know this isn't a true performance test but I'm confounded by my results.

Thanks,

Justin
