[PolyORB-users] Polyorb Performance

[Sturm, Peter]

Hello,

I'm testing the performance (data throughput) of the Polyorb version GPL
2009.

Therefore I modified the examples in examples/cobra/echo to send 2 MB
string data multiple times to the server and transmit it back to the
client.

I used the gcc/gnat version 4.4.3 for compiling.

The measured bandwidth was around 6 MB/sec (client & server on same pc
system). This seems to be very poor compared with other CORBA
implementations.

Testing with TAO results to a bandwidth of 200 MB/s.


Does anybody have experience of the Polyorb performance?
Could it be a misconfiguration of the Polyorb installation?

I tried to customize the polyorb.conf entries,

- tcp.nodelay
- polyorb.protocols.iiop.giop.1.X.locate_then_request
- polyorb.protocols.iiop.giop.1.X.max_message_size

but the changes had no effect or changing the max_message_size leads to
worse results.

Testing using version 2.4.0 or an actual snapshot of the subversion
archive led to similar results.


Any ideas?
