I run 1536/256 ADSL here and found that a figure or 205Kb is the

full bandwidth i'm paying for. If you have 256Kb try changing this
figure and you might find you gain some extra speed.
Yeah, i know that i'm not getting the max out of my connection, but if
i set it to anything over 200Kbit i get more lag/delay on the connection.
Thats odd, the only thing I can think of is a shoddy contention ratio or
something is slightly misconfigured. One way to check what is actually
going on is to continually run pfctl -sq -v , this will show you how
full your queue is and how many packets have been dropped.
I had a play a while ago with the qlimit but I had it added into the
"altq on rl1......" line, oddly it never changed a thing and never
gave an error. Since seeing your qlimit statements i've been playing
with it for the past couple of days and working on tuning and found a
qlimit of 1 serverly limited queues and they never saw full bandwith
potential. I found a good figure for me was 10 as opposed to a
standard 50. My testing of the qlimit number had me pinging a local
site while uploading with Azurues and watching its graph.
What where your ping-times?
Another thing: i'm trying to prioritize my outgoing icmp-packets.. and
if I send 4 pings i get "8 packets" in pfctl -vs rules on the rule i
made. I would think that "4 packets" would be more correct? *confused*
My ping times normally were 29-30ms but ranged from about 80-130ms while
uploading flat out with Azureus although I found the true trial to be
how well I could play games online. It turns out that it was *slightly*
more laggy but not to bad on a whole. I'm not sure why you would be
seeing 8 packets when you send 4 pings, I just did a test here and 4
pings definately equals 4 packets. Could this be related to you not
being able to set your connection speed any higher ??
If you want email me your rules off list and i'll have a look and see if
I can see any problems, sometimes a fresh set of eyes helps with simple
errors.
Matt.
