I guess a better question is: How much traffic are you pushing? I've
seen LVS-NAT do 10-12 million page views a month with three dual
3.2GHz P4's. I've seen LVS-DR (it might have been LVS-TUN) do 30
million page views a month on four dual 750MHz Xeons with nearly no
load at all.
If you're not serving more than the above and you have 20 servers
you're over killing or your code needs a review.

Dear All,
Really ultramonkey is working well with RHEL v4 (kernel
2.6.9) in
my cluster environment.... My question is what's the exteme limit
of LVS
NAT
How many real servers it can support.How much throughput it can
deliver. How much it's connection limit, how can i increase maximum
connections.
As i read the document in linuxvirtualserver.org , LVS NAT works
fine in
around 20 real servers.
But what would be happened if i add more than 30 real servers in
cluster.
is it hard limit or what ? , because i am using medium range server
(dell
poweredge 1850) with Gbit switch , so network should not be
bottleneck.
even director's configuration is dual P-4 2.4 Ghz processor with 4 GB
RAM.
To improve the efficiency of director what should i do, like
increasing
socket window size , MTU value of NIC ?
Your experience will help me
