[Solved]Why copy within local network creates latency on WAN?
-
Hi,
I'm not sure if it's related to the Traffic Shaping but when I copy a file from one server to another with SCP ( both on the local network ) it increases latency on the WAN.
See bellow:root@my:~$ scp debian6.iso root@192.168.0.21:/dev/null debian6.iso 3% 95MB 9.7MB/s 04:19 ETA root@my:~# ping google.com PING google.com (74.125.226.51) 56(84) bytes of data. 64 bytes from 74.125.226.51: icmp_req=1 ttl=58 time=13.2 ms 64 bytes from 74.125.226.51: icmp_req=2 ttl=58 time=14.3 ms 64 bytes from 74.125.226.51: icmp_req=3 ttl=58 time=14.3 ms 64 bytes from 74.125.226.51: icmp_req=4 ttl=57 time=10.7 ms 64 bytes from 74.125.226.51: icmp_req=5 ttl=58 time=15.0 ms And without SCP: root@my:~# ping google.com PING google.com (74.125.226.49) 56(84) bytes of data. 64 bytes from 74.125.226.49: icmp_req=1 ttl=58 time=8.18 ms 64 bytes from 74.125.226.49: icmp_req=2 ttl=58 time=8.14 ms 64 bytes from 74.125.226.49: icmp_req=3 ttl=58 time=8.17 ms 64 bytes from 74.125.226.49: icmp_req=4 ttl=58 time=8.24 ms 64 bytes from 74.125.226.49: icmp_req=5 ttl=58 time=8.26 msAny suggestions?
Thank you,

do you have bridge?

No, it's a simple setup:
192.168.0.0/24 ( LAN ) –| PFSENSE |--- xxx.xxx.xxx.xxx/29 ( WAN )
I just used the Traffic Shaping wizzard to limit bandwith for our VOIP on the LAN. It doesn't seems to be a CPU issue, I checked it and it's arround 20%~ during high bandwith load.

Where are you initiating the pins from?

I think I know where the problem comes from, it's just the pipe on my machine is probably full, all ping came from my laptop.
I'm changing the status of the post to [solved] :)
