Gargoyle Forum

Hello. Your help is appreciated.

Does bandwidth monitoring have significant overhead?

I use Gargoyle for two thing. Bandwidth monitoring and QoS for VOIP. I no longer need bandwidth monitoring; I just need QoS.

Can I turn off bandwidth monitoring? Is there an advantage of turning it off?

Thanks,

Allan

Hi Allan,

Yes you can.

Currently you can't do it via the GUI (it used to be in the Services Manager plugin) but you can do it via the command line.
The Bandwidth monitoring will remain disabled until you reboot the router.

For a more permanent disable you will need to either remove the script from or instead put the above 2 commands into Bandwidth Monitoring does have overhead, I would consider it only to be an issue on older routers that are restricted by small memory or slow CPU's or that you have a very fast bandwidth pipe that you want to test for throughput comparison. Chances are that if your router is capable of running Gargoyle 1.9.x then it will be able to hadle traffic without bandwidth monitoring being disabled.

I know it's been a long time, but I finally had some time to look into my speed issues.

I disconnected everything else from the network. It's only the cable modem to the router to my computer.
No WiFi. Nothing on for restrictions or quotas. No QoS.
Xfinity speed paid for is 200 down/10 up

rebooted router. I ran each speed test three times and averaged the results (which were very close within each set). Upload bandwidth for QoS set to 12000 kbits/s

Monitoring off
QoS upload off
229 /12 Mbps

Monitoring off
QoS upload on
212 /11 Mbps

Monitoring on
QoS upload off
126 /12 Mbps

Monitoring on
QoS upload on
93 / 11 Mbps

Please help me interpret these results, but to me, bandwidth monitoring is really killing my connection.

Can I use QoS without monitoring? All I really wanted was QoS. I might play with ACC later.


Background
Gargoyle Version:1.8.1
Model:NETGEAR WNDR3800
Device Configuration:Gateway
Memory Usage:20.2MB / 123.4MB (16.4%)

as far as I know, yes you can. But you can’t use quotas or restrictions. And the bandwidth monitoring is obviously useless.

The results are based on the limit of your CPU. The bandwidth module takes quite a bit of overhead at higher speeds. A faster router will route more data before hitting this cap.

great! thanks
