Jeff -----Original Message----- From: Eric van Gyzen [mailto:vangyzen@FreeBSD.org]=20 Sent: Thursday, March 17, 2016 8:23 AM To: Alan Somers ; Pieper, Jeffrey E Cc: FreeBSD Net ; Jack Vogel Subject: Re: TSO test Alan, That does sound useful. As one complication, "vmstat -i" shows the interrupt rate since boot. Either the test would need to reboot between each iteration, or vmstat would need to be improved to show the "recent" rate. The latter would be a much welcome improvement, in my humble opinion= .
