SFQ would be the better option in most cases since it prioritizes packets based on flows in a round-robin fashion. Essentially, it allows multiple flows to receive equal bandwidth in a given class. PFIFO would allow one flow to starve out the rest.

Hi to all, i'm following this guide (http://www.opalsoft.net/qos/DS-28.htm), is very detailed, but i'm a bit confused about queuing disciplinse of leaf classes. In this guide the author uses PFIFO (see the scheme that i attached at message) in this way: # tc class add dev eth0 parent 1:21 handle 210: pfifo lmit 10 # tc class add dev eth0 parent 1:22 handle 220: pfifo lmit 10 # tc class add dev eth0 parent 1:23 handle 230: pfifo lmit 10 # tc class add dev eth0 parent 1:24 handle 240: pfifo lmit 10 # tc class add dev eth0 parent 1:31 handle 310: pfifo lmit 10 # tc class add dev eth0 parent 1:32 handle 320: pfifo lmit 10 # tc class add dev eth0 parent 1:33 handle 330: pfifo lmit 10 # tc class add dev eth0 parent 1:34 handle 340: pfifo lmit 10 But is not better use SFQ, like this? # tc class add dev eth0 parent 1:21 handle 210: sfq preturb 10 # tc class add dev eth0 parent 1:22 handle 220: sfq preturb 10 # tc class add dev eth0 parent 1:23 handle 230: sfq preturb 10 . . . What's the real difference?
