Slow network throughput NMS -> 2mb / Sec

[André Jager <an...@spe-unna.de>]

Hello,

I use ActiveMQ (4.1.1) in conjunction with C# and am experiencing very bad
network performance.

I wrote a test program to test the performance. The client sends 4kb Byte
Messages, the server reads the queue, acknowledges the messages and discards
the content. Client and server are written in C# using the latest NMS /
ActiveMQ client.

Since I was suspecting DOTNET Sockets to be a bottleneck, I wrote a small
Client / Server program sending 4 kb blocks using DOTNET sockets. The Client
and Server are written in C#.

In both cases I send the same data, a 700 mb stream. With ActiveMQ I can put
through 2 mb / Sec, with the bare metal socket implementation in DOTNET I
get a 27 mb / Sec throughput (1gb network).

At the server, when I run the ActiveMQ test client, I see the JAVA VM jump
to 80% CPU (for what it is, I have no experience with JAVA).

Is there a general performance problem or is there a performance problem in
conjunction with NMS.

Who wrote NMS, maybe we can contribute to the project solving these
performance issues (if they are present in NMS).

thanks,
André Jager

We are always grateful of contributions - it would be great if you  
could help out - the community of users and developers is what apache  
projects are about afterall.


cheers,

Rob
