We are looking at tuning an igb (Intel 82575 based) device for absolutely fastest latency (at the cost of some throughput/overhead of course).
It seems that the interrupt timers are not available from the standard drivers official documentation: http://docs.sun.com/app/docs/doc/816-5177/6mbbc4g6c?l=Ja&a=view Although there is plenty documentation on the tuning that should be possible from Intel at: http://download.intel.com/design/network/applnots/ap450.pdf We'd like to be able to tune this per port, as we have one port where we only need low latency, the other ports may have mixed performance characteristics. Are there any way to manage/configure the interrupt coalescing for these newer ports? On the previous x4150, it was possible by configuring the e1000g interface, see: http://blogs.sun.com/simons/entry/solaris_tcp_latency_for_hpc for details. Any ideas? -- This message posted from opensolaris.org _______________________________________________ networking-discuss mailing list [email protected]
