Do you have selective-ack enabled? Try these and see if your TCP is better: tcp selective-ack tcp window-size 65535 We had issues with this in the past at my prior employer and these options solved much of it. I’m trying to recall if we ever got the window scaling stuff fixed but I forget. I think their TCP stack didn’t do window scaling if you tcpdump it. It might be different in eXR. - Jared _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
