[Ccrtp-devel] ccrtp version 0.9 win2k performance

[Yang, Xu]

Dear David, Fed,
I am not sure if this is caused by my poor system (pII400 512M mem) or by my
badly tuning. When I send 1000 pkts (512 byte each), I only received ~700 of
them. And the CPU usage is 100% all the time. The rtpsend and rtplisten
example is used during the test. the sender has the following segment in the
code:
                for ( int i = 0; i < count ; i++ ) {
                        putPacket(i*1600,RTP_PAYLOAD_PCMU,
                                  data,strlen((char *)data) + 1);
                        cout << "write" << i << " packets" << endl;
                        ccxx_sleep(200);
                }
Is this the same on linux?

While I try to build a rtp router by combine the rtpsend and rtplisten code,
I lost even more.
Here is the router class, any suggestion? comments?

Thanks
