SOAP API Slow first connection

Hi Everyone,

I am having some trouble with my .net integration with my salesforce org. Namely the first connection to through the API.

The first connection can take anywhere from 8 - 12 seconds which is quite a while considering its a simple lead creation form, after making the initial connection the interaction with my API is quite fast. I have searched everywhere for a solution to this problem and come up with nothing.

Any suggestions?

The first call being slow with WCF is documented in Accessing Force.com SOAP Endpoints with .NET (https://developer.salesforce.com/blogs/developer-relations/2014/09/accessing-force-com-soap-endpoints-net.html) and Why is the first WCF client call slow? (http://stackoverflow.com/q/10859832/54026)

If you don't want to switch to using a Web Reference have a look at How to: Improve the Startup Time of WCF Client Applications using the XmlSerializer (https://msdn.microsoft.com/en-us/library/aa751883(v=vs.110).aspx)

Yes, with SOAP first connection will always sucks big time. My recommendation would be create a simple REST class in APEX which will create a lead and access the rest url in .net program and post the data. I personally use this method and it's really quick.

Good luck :)
