----------------------------------
Assignee: Jens Geyer
> Csharp slow ?
> -------------
>
> Key: THRIFT-2567
> URL: https://issues.apache.org/jira/browse/THRIFT-2567
> Project: Thrift
> Issue Type: Question
> Components: C# - Library
> Affects Versions: 1.0
> Reporter: Martin Vogt
> Assignee: Jens Geyer
> Priority: Minor
> Attachments: Client.cs, Server.cs
>
>
> Hello,
> I have a simple csharp server/client for performance tests,
> something like this
> {quote}
> service {
> binary getData();
> }
> {quote}
> which returns a 1MB buffer.(git snapshot from a few days ago).
> A thrift call client->server takes 8ms
> according to stopWatch.Elapsed. The same client->server
> implemented from here(modified of course):
> {quote}
> http://www.java2s.com/Code/CSharp/Network/SimpleTcpClient.htm
> http://www.java2s.com/Code/CSharp/Network/SimpleTcpServer.htm
> {quote}
> takes ~1ms. (Factor 8 faster, than the thrift client/server, all localhost
> connections on windows)
> I tried to narrow it down where the actual problem is, but without
> luck so far.
> - Its not the binary stream creation during unmarshall:
> {quote}
> // pseudocode
> byte[] getData() {
> len=iprot.readi32()
> byte[] x=new byte[len]
> iprot.readAll(x,len);
> return x;
> }
> {quote}
>
> It _looks_ that its in the thrift c# library classes (TSocket,etc..),
> but up to now I haven't found an explanation for the
> differences.
