Playing with fq_codel in 2.4

HeatmiserNYC

Cool, thanks for replying.

Yes, I get about 125-130 down when I set my limiter to 143mb (95%). My connection without the limiter will tend to burst initially to a bit over 200mb according to testmy.net. I have a simple setup following the guide detailed in the first post.

I use the VPN for all outbound traffic, it's not a separate situation.

I have tried traffic shaping before and this has been true for any configuration I have ever tried. If I try to shape close to my line speed it takes about 20mb off the top. How do you not use a bandwidth limit? Adding a delay limit in the field doesn't take.

Just need a successful example of this to get running…

Again, thanks.

Perhaps your speed drop is related to overhead like VPN, TCP, etc. I assume you are referring to goodput bitrates?

On downloads you will commonly see below the configured bitrate because each time you hit the limit pfSense will tell the sender to slow down below the limit. Personally, I found very little useful benefit by limiting downloads because my ISP has minimal bufferbloat and allowing them to do the rate-limiting gives me 100% speeds.

What about to try to move shaper/limiters from LAN side to VPN side firewall rules?

HeatmiserNYC

That's an idea, I'll give that a shot!

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

HeatmiserNYC

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…

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.
