-----------------------------------
Summary: 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
Priority: Minor
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.
