I thought they were both default, but it seems there was a forgotten change on sanlab: SAN2:~# sed -e '/^#/d;/^$/d' </kernel/drv/ixgbe.conf SAN2:~# SAN-LAB:~# sed -e '/^#/d;/^$/d' </kernel/drv/ixgbe.conf intr_throttling = 8; SAN-LAB:~# Hmm. Well commenting that out doesn't make a difference (ran update-archive and did a full cold reboot - still getting a max of 530Mbit/s with a pretty much identical flamegraph as before) I've double checked the dladm show-linkprop output is identical for both the ixgbe's and the aggregate; the only difference is cpus-effective for the aggregate: 0-9,11-15 on SAN2 (i.e. all but one hyperthread ??) versus 0-11 on SAN-LAB (i.e. all cpus) ------------------------------------------- illumos-discuss Archives: https://www.listbox.com/member/archive/182180/=now RSS Feed: https://www.listbox.com/member/archive/rss/182180/21175430-2e6923be Modify Your Subscription: https://www.listbox.com/member/?member_id=21175430&id_secret=21175430-6a77cda4 Powered by Listbox: http://www.listbox.com
