When I set up a test environment with LVS and I run testLVS,
how can I find out the bottleneck of this system?
On a 10 MBps network I see about 2000 packets per second arriving
at the server with "show_traffic". On the redirector I find 14,000.
How can this be? Collisions happen, but not that much.
I use TCP, if we have 14,000 packet with 40 Byte, that would be
5 MBps. This is not much.
Where's the bottleneck? And why do only 1/3 of the packets arrive
on the server? (14,000 on the redit -> 7000 in and 7000 out, but
only 2000 arrive).
In a world without walls and fences - who needs windows and gates?
