I did the measurements on a non-saturated link, I'm sure of this because when I ipfw flush, ipfw queue flush, the ping goes back to normal. I have no packet loss either way, whether dummynet is configured or not. An added note, this is running on an 533 MHz alpha with a de type card hooked to the dsl modem running at 10Mbit/sec full duplex (dsl connection is rated at 608Kbit/s down and 128 Kbit/s up), and an xl type card connected to the internal net running at 100Mbit/sec Full duplex. My configuration looks like this:
ipfw add queue 1 ip from any to x.x.x.x/24 in via de0 ipfw add queue 2 ip from x.x.x.x/24 to any out via de0 ipfw pipe 1 config bw 570Kbit/s queue 47 ipfw pipe 2 config bw 118Kbit/s queue 10 ipfw queue 1 config pipe 1 weight 40 mask dst-ip 0x000000ff ipfw queue 2 config pipe 2 weight 40 mask src-ip 0x000000ff I set it to 570Kbit/s download because this is the top download speed I measured (I get this speed to pretty much every site I download from, to arrive at this number I downloaded a file 2 times from a site that gave me around 62Kbytes/sec (my max speed), then I turned on queueing with successively larger bw values for pipe 1 until I could attain my top speed, then I added 10 Kbit/s just to be sure that I was getting the full wirespeed my connection would support. I did this for the upstream as well) Thanks for your help. Ken To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
