Sending files over TCP/ .NET SSLStream is slow/not working

Question

Im writing an Server/Client Application which works with SSL(over SSLStream), which has to do many things(not only file receiving/sending). Currently, It works

Answer 1

Your problem stems from the fact that you are performing what is essentially a binary operation through a text protocol and you are exacerbating that problem by doing it over an encrypted channel. I'm not going to re-invent this for you, but here are some options...

1. Consider converting to an HTTPS client/server model instead of reinventing the wheel. This will give you a well-defined model for PUT/GET operations on files.

2. If you can not (or will not) convert to HTTPS, consider other client/server libraries that provide a secure transport and well-defined protocol for binary data. For example, I often use protobuf-csharp-port and protobuf-csharp-rpc to provide a secure protocol and transport within our datacenter or local network.

3. If you are stuck with your transport being a raw SslStream, try using a well-defined and proven binary serialization framework like protobuf-csharp-port or protobuf-net to define your protocol.

4. Lastly, if you must continue with the framework you have, try some http-like tricks. Write a name/value pair as text that defines the raw-binary content that follows.
