X-BeenThere: freebsd-ipfw@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: IPFW Technical Discussions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 01 Jan 2007 17:42:28 -0000 I see in the dummynet man page: Generally, the following options are required: options IPFIREWALL options DUMMYNET options HZ=1000 # strongly recommended But all of the NOTES and other documentation only mention setting the HZ value in conjunction with DEVICE_POLLING. The man page for dummynet is dated October 2002. So the question is: circa 6.1, does it matter anymore to set an HZ value if you aren't using DEVICE_POLLING ? If so, why ? I understand the benefit when used with DEVICE_POLLING, but not for dummynet ... Thanks!
