Question

Again a question about compression on wcf services.
I’m using netnamedpipe binding to send some entity objects to my calling application.
I know, that’s a bad idea, but that’s the way my customer wants it to be implemented.

So right now, I have to send about 45000 datasets (entity objects) via netnamedpipe.
That’s really really slow. I’ve implemented a class which compresses the data objects to
byte[] before sending, but 45000 sets are still taking ’bout 45 seconds to send/receive.

I’m compressing like this:

public static byte[] Compress<T>(T data)
{
    byte[] result = null;
    using (var memory = new MemoryStream())
    {
        using (var zip = new DeflateStream(memory, CompressionMode.Compress, true))
        {
            var formatter = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
            formatter.Serialize(zip, data);
        }
        result = memory.ToArray();
    }
    return result;
}

Is there a way to improve that? 45 seconds are too much 🙁 I think, main reason could be serialization of my entity objects.. but how to speed that up?

Answer 1

try using DTO pattern. Send only those fields which are required
