Attaining full network utilization with an Equalizer application is rare. You can use the netperf tool which comes with the distribution to test the throughput of the eq::net layer. > > I observed that the transfer time it's high only in certain moments, > for example: 5 seconds the system is running on ~15FPS, and then the > transfer time increases for a short period, and the fps is 2-3.. > (tested with a 320x240 config). Do you change the camera position? If so, varying compression ratios can be the cause. Or does the framerate stutter occasionally from 15 to 3 FPS? If yes, then my guess would be that network collisions cause retransmits which take too long. There are a number of TCP parameters to test, but this depends on your hardware and software. Wireshark and google are your friends to analyze this. > In this case should a better compression improve the overall > performance? In any case a better compression should improve the overall performance. A Gigabit ethernet setup will however give you the best performance increase for the money (and work). In your case it seems there is another issue, but it's hard to analyze remotely.
