Hello,

I've already read this thread:
http://archive.linuxvirtualserver.org/html/lvs-users/2007-02/msg00106.html
Our problem is pretty similar.

In short:
We have a geographically distributed LVS-Tun setup. The download
speeds I get:

from Client A via LVS: 10KB/sec
from Client A directly from REALSERVER: 300KB/sec

from Client B via LVS: 500KB/sec
from Client B directly from REALSERVER: 1000KB/sec

speed from Client A to DIRETOR is the same as from Client B
speed from DIRETOR to Client A is the same as to Client A

Clients A and B are located in different cities.
Calls in all 4 cases are exactly the same (GET HTTP).

The question is why Client A get such difference in speed (10KB vs
300KB) when he's accessing the same content via LVS and bypassing it?

Were to look? What to tcpdump?

- 
Best regards,
Fry
