Calling web service from compact framework too slow

i have an application with CF3.5 Calling of simple webMethod like bool Ping(Guid id){return true;} takes ~ 1.8 sec (windows client answer takes ~ 0.3 sec)

As i read, there is way to optimize speed by gzip - but it seems开发者_JAVA技巧 here we have nothig to compress... Is there any other ideas to increase speed?

thanks

When calling Web Services from the Compact Framework, the first call is always painfully slow as the CF has to JIT and instatiate all of the proxy pieces required to make the call. Typically you'll see a slow first call and then reasonable call times after that. A typical workaround is to have the app spin up a worker thread at startup that makes a call to the web service - even if it just calls a stub method - to get all of that work done in the background before you need to make a "real" call.
