Wrong limiter speed
-
il get in touch as soon as i can do it ! but honestly
this is getting far deeper for something that is created on a simple click. i means creating a limiter suppose to be easy as 123.
IMO this is getthing ridiculous ! if so many thing need to be modify on a single limiter limitation, why when your press APPLY they don’t run a script to set the right adjustement ! imagine you need to forward a port, and then you have to modify this and that TO MAKE IT WORK ! That will be irrelevent or if you prefer useless function !anyway ill get back to you
youre help is please ! -

cuz the limiter does what it is supposed to do !
here and on some other boxesto be honest i can not see the use case for gettin as deep as shown here
an any set upmaybe u can help me out here explainin whats the urgent need
-
nothing urgent bro !
simple !let say your 50 on a network, 5 start a download !
the gateway goes down and packetloss occur on high level !with the limiter nothing of that appends because gateway still have room to breathed and nothing goes down on the gateway.
that the big advantage of the limiter.

For us, we were setting it up in a church. They stream several services at the same time. To accommodate this we brought in a second WAN and route specific devices out that interface. To prevent each machine from taking up too much of the bandwidth and affecting the other streams we limit their max usage. In this case it is a 35Mbps upload split between 4 devices, each with a 10Mbps upload limit but only needing 5Mbps for the streams. For example, there are 4 streams going and someone decides to (unwisely and against policy) upload a previous stream to the platform from one of the streaming boxes. Normally that would use up all possible bandwidth but with a limiter in place that particular device is unable to affect the other streams. If the full 10Mbps is used then there is still 25Mbps remaining for the other 3 devices. If each of those 3 devices is using 5Mbps then they are only using 15Mbps out of the 25Mbps, leaving a cushion of 10Mbps. Technically, in this case, 3 users could be offending and the 4th stream should still run fine. Without the limiter just one bad actor could ruin it for everyone else.

Could you post this as a screenshot, cropped to just the config section? I'm having a hard time following and duplicating. Thanks.

@Jimbohello The problem is that traffic shaping isn't a one size fits all kinda setup. Default settings is more likely to be something that works with bandwidths likely to be 100 Mb/s or below because that is what general use cases were, when the settings were chosen. These settings doesn't take other factors, like different types of hardware setup used or what type of internet connection is used (COAX, xDSL, PTP fiber, GPON fiber), into consideration.
This also means that the above 900 Mb/s, like in your case, doesn't show the expected performance because the default settings just doesn't work well for that kinda of bandwidth. So this means that tuning is necessary to either obtain the maximum performance which is possible or what is expected as set by the limiter. Once done tuning you can leave it alone and don't bother with it again. -
thank’s for the explaination!
verry appreciate

@Jimbohello can you please run "sysctl hw.em" and "sysctl dev.em" in the command prompt and paste the result.

OK
I m Readin and learningA Lot
Thank you!!! -
@Jimbohello I just assume you haven't tried this before so i will list the following out in simple steps:
-
go to Diagnostics / Edit File
-
press browse and find boot/loader.conf
-
add .local so you get the string "/boot/loader.conf.local" and press save
-
press browse then find and click on loader.conf.local
-
delete the commands within loader.conf.local and add the following:
hw.em.eee_setting="0"
hw.em.rx_process_limit="-1"
hw.em.txd="2048"
hw.em.rxd="2048"
net.link.ifqmaxlen="4096" -
hit save and reboot

WOW thank's for your precious help
on a limiter of 799 i can same as yesterday so close to 735
so no change !
up to date the queue lenght 100 was the best tunning
can you please provide fast explanation on these Tuning you provide !
i know that *.local usually will load the *.conf and override.
But what are these tunning ??
THANK'S -
@bobbenheim
1 came close to 760 !
i can easy live with that.
that's the best setting so far ! it's almost the limiter setting 799 ! the accuracy bettewn 760/799 is damw better !
BRAVO !
explaination on your tunning steel be please ! GRACIAS -
Try and keep a download running for some minutes and check monitoring you might have the correct limitation but the speedtest are not taking overhead into consideration.
Need to get back to you on those settings, it's time for some sleep :) -
Found a couple of links that explains what the following does:
hw.em.eee_setting
https://www.freebsd.org/cgi/man.cgi?em(4)hw.em.rx_process_limit
hw.em.rxd
hw.em.txd
net.link.ifqmaxlen
https://calomel.org/freebsd_network_tuning.html
look under local.conf and just ignore that he uses an Intel nic which uses the igb driver instead of the em driver. -
@bobbenheim
i look at the link you send me
hw.em.eee_setting="0"
mean that energy is enabled
to be at full (no Energy Efficient Ethernet) always should it be disable =1
to force the nic to be at maximum !?? -
@Jimbohello Didn't take notice of that, but you can give it a try and change it back to see if it makes a difference. But so far it seems that a lot of people have misunderstood that one if "1" is disable, i wouldn't know since i don't use the em driver and therefore haven't tested it.
-
@bobbenheim
because i'm french
correct me if i'm wronghttps://www.freebsd.org/cgi/man.cgi?em(4)
hw.em.eee_setting Disable or enable Energy Efficient Ethernet. Default 1 (dis- abled).so 1 = disabled
wright ??
