Hi! To be continued...
I replaced 82598 (2 cx4 ports) with 82599 (2 sfp+ ports) without any configuration changes. The same host, same system, same tuning, same load and traffic. Was (82598): # vmstat -i interrupt total rate irq19: atapci0 1667110 0 cpu0: timer 3386721810 328 irq256: ix0:que 0 3395843376 329 irq257: ix0:que 1 2642665824 256 irq258: ix0:que 2 2838302235 275 irq259: ix0:que 3 2176207954 211 irq260: ix0:link 18 0 irq261: ix1:que 0 282359321 27 irq262: ix1:que 1 3989170496 387 irq263: ix1:que 2 375956573 36 irq264: ix1:que 3 3966352151 384 irq265: ix1:link 1 0 irq266: em0:rx 0 10283114 0 irq269: em1:rx 0 10283114 0 cpu3: timer 3386697130 328 cpu1: timer 3386709028 328 cpu2: timer 3386700908 328 Total 33235920163 3225 Now (82599): # vmstat -i interrupt total rate irq1: atkbd0 353 1 irq19: atapci0 1368 3 cpu0: timer 682557 1978 irq256: ix0:que 0 3555342 10305 irq257: ix0:que 1 3120223 9044 irq258: ix0:que 2 3408333 9879 irq259: ix0:que 3 3279717 9506 irq260: ix0:link 4 0 irq261: ix1:que 0 2905248 8421 irq262: ix1:que 1 2647858 7674 irq263: ix1:que 2 2411908 6991 irq264: ix1:que 3 2319469 6723 irq265: ix1:link 3 0 irq266: em0:rx 0 338 0 irq269: em1:rx 0 338 0 cpu1: timer 682529 1978 cpu2: timer 682527 1978 cpu3: timer 682527 1978 Total 26380642 76465 Why interrupt count is so huge? What's wrong with this card (or with driver)? -- View this message in context: http://freebsd.1045724.n5.nabble.com/Too-much-interrupts-on-ixgbe-tp4931883p4988068.html Sent from the freebsd-net mailing list archive at Nabble.com. _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
