Terrible performance with lvs_dr

["Alexander Storman" <alex@xxxxxxxxxxxxx>]

I am just setting up my first lvs, and I am encountering a problem with my
setup that I have not yet read anything about...

I have setup the lvs with direct routing (although I have tried it with NAT
as well, and I have the same problems) with the real servers having
different network routes (both the director and the real servers have 2
nics).  It works, but the performance is awful.
Ping imes from the Director to the Realservers IP's are around 2000ms, bad
by any measure, let alone 2 machines connected to the same hub.
Has anyone had this issue crop up before??  I am going to assume that it is
a simple config issue that I have overlooked, but I can't be sure....

Here is the setup, IP's have been changed to protect the innocent.
