WCF OneWay service slows down when aspNetCompatibilityEnabled is set to false


WCF OneWay service slows down when aspNetCompatibilityEnabled is set to false

this will help If your application is hosted in IIS and if you set the aspNetCompatibilityEnabled='false' the requests will not flow through the ASP.NET http pipeline. One of the reason for the slow behavior could be, since the requests are not taking advantage of the pipeline, IIS is taking some time to run the scripts necessary to receive and pass the request to WCF. WCF by default only process one request at a time until you specify a different concurrency level. Other requests have to wait till the previous request is processed. It is the ASP.NET HTTP pipeline that is holding the request queue and processing it one at a time. I believe in this case since ASP.NET HTTP pipeline advantage is lost the the non ASP.NET pipeline is not handling the request queue properly. I hope this answers your questions. Some additional documentation on this are mentioned below

I wish this help you I found my own answer. There was some code between SP1 and SP2 that accesses the Context.Current.Request object. Commenting it out fixes my issue.
Conclusion? It seems the Request object is unavailable if OneWay=true. Strange though that setting makes the object available.

will be helpful for those in need Figured this out. First I turned on tracing following these instructions: http://msdn.microsoft.com/en-us/library/bb885203.aspx
This showed me that when oneWay is turned on I was getting security exceptions. (I don't really understand why I would get that only for oneWay but whatever).

like below fixes the issue Unfortunately, that's not possible. ServiceHostingEnvironment.AspNetCompatibilityEnabled is a static member, hence it always applies to all services within one AppDomain.
If you definitely don't want AspNetCompatibility enabled for some services they have to be hosted in a different (IIS) app. Could still be within the same site, though! Would that work for your scenario?
