when i run the command " roslaunch pointgrey_camera_driver camera.launch", i meet the warning:
Warning: Default Linux receive buffer setting is lower than expected. You may experience poor GEV streaming performance. (Related Related KB : http://www.ptgrey.com/kb/10016)
how can i solve this problem?thank you very much!

The pointgrey page is unfortunately not reachable anymore. I increased the receive buffer with the following two commands:
sudo sysctl -w net.core.rmem_default=31457280
sudo sysctl -w net.core.rmem_max=33554432

If this does not help try also to set the MTU of the desired connection (eth0 or similar) to 9000:
sudo ip link set dev eth0 mtu 9000

Hope this helps!
