Wrong limiter speed

bobbenheim

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

@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

Jimbohello

@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.

Jimbohello

@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 !??

bobbenheim

@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.

Jimbohello

@bobbenheim
because i'm french
correct me if i'm wrong

https://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 ??

bobbenheim

@Jimbohello yes i would interpret it that way

Jimbohello

@bobbenheim
