Playing with fq_codel in 2.4

HeatmiserNYC

Yea, that didn't work.

w0w

Just for testing purpose, try to change bw limiting to delay limiting :

pipe 1 config delay 0ms

for both pipes

Sorry gone for a few days, vacation.

I gave that a shot by changing the /tmp file, it doesn't seem to have an affect. I am only changing the /tmp file, maybe it needs to be rebooted and hardcoded into the file? The only reason I haven't done this is because I haven't seen the results everybody is reporting…

w0w

Yes it's need to be rebooted or reloaded with```
/etc/rc.reload_all

After you did that run the following command```
ipfw sched show
```and you should see something like```
00001: unlimited         0 ms burst 0
```for the both pipes you have.

Yes, all relatively simple and you've been great at walking through the steps you put in place.

I'm getting this for both pipes.

00003: unlimited 0 ms burst 0

00004: unlimited 0 ms burst 0

Yet I can't get better than a B rating for bufferbloat, which is the same if I literally do nothing at all….

w0w

But what about VPN bandwidth? Are you still getting 120Mbps?

HeatmiserNYC

That part HAS improved, looks like it does get about 145-ish or so which is about right. It just does nothing for bufferbloat.

w0w

Can you post the full output of```
ipfw sched show

I'd like to look at implementing this, but I was wondering

Anyone know the status of pfsync + limiters?

What was the last status you know? :D

moscato359

The last status I know is that the pfsense book says not to use pfsync and limiters together, but doesn't explain why

This is actual. https://redmine.pfsense.org/issues/4310 have 0% progress.

Is there any chance fq_codel will make it into the 2.4 GUI in limiters?

w0w

Definitely not!
They are keeping eyes on it, but currently no plans, no moves, AFAIK.

Darn. I'm thinking about switching back to pfSense but I really want fq_codel.

fq_codel, the ZFS of AQMs, or nearly. Cake aims to be the "ZFS", but close enough.

Is the command of "ipfw sched 1 config pipe 1 type fq_codel && ipfw sched 2 config pipe 2 type fq_codel" the same if I only have 2 root limiters? Both of them are root limiters one has a mask of source and the other has a mask of destination.

I would like to try this out but wondering if the command is different for just root limiters without "child" queues. Obviously I am highly dependent on the gui I am a bit confused with the ipfw command since it references both sched and pipe.

Thanks for any reply!

w0w

TS sample is for the root limiters also, if you have some troubles understanding, post the content of your /tmp/rules.limiter

superbree

here is the content of my /tmp/rules.limiter

pipe 1 config bw 100Mb mask dst-ip6 /128 dst-ip 0xffffffff

pipe 2 config bw 10Mb mask src-ip6 /128 src-ip 0xffffffff

I need help with the ipfw command to enable fq_codel on pipes 1 and 2 because i don't have any child queues.

thanks in advance
