Yes. Anything you can do to a) increase buffer (traditionally in Catalyst, EX, you can win quite bit more buffers by removing queues) b) increase egress rate (LACP to the host may help) Will help a little bit. > Based on the output provided what you suggest to change ? > I also understand this kind of change is traffic affecting. I'm not familiar with QFX tuning, but it should be fairly easy to find and test how you can increase buffers. I think your goal#1 should be move to single BE queue, and try to assign everything there and secondary goal is to add another high priority class and give it a little bit of a buffer. > I also need to understand how shared buffer queues on QFX are attached to COS > queues. Yes. I also don't know this, and I'm not sure how much room for tinkering there is, I know in catalyst and EX some gains over default config can be made, which have significant improvement when boxes have been deployed in the wrong application. -- ++ytti _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
