Question
.NET WebService call from windows application uses a lot of traffic
I have a C# winforms app (.NET 2.0) that is calling a web service on a server (IIS6).
I am trying to make the web service call as efficient as possible, but the network traffic is about 3 time as much as the actual data sent, and I don't know why...
The call to the webmethod passes a byte array which is a compressed stream of bytes.
for example: (actual tested results)
I want to pass a byte array of 1231377 bytes.
I compress the byte array using sharpziblib down to 828348 bytes.
the http post for the web service calls Content-Length is 1104804
the network adapters "Bytes Transmitted" increases by 2289182 bytes
so, for some reason my submission of 900K of data requires the transmission of more than 2.2MB - I expect some overhead but this is excessive.
any suggestions or reasons as to why this is would be greatly appreciated.

have a look at this - http://bytes.com/forum/thr
it seems that the default data encoding over the web service is base64 - which is known to drasticly increase the size of the data package. look for alternative ways to perform your action than with plain non-compressed WS requests.
also, why does a single request post 900K of data? thats sounds like too much?
