Your figures sound very low.
We have several customers running at 10K/s+ on fairly stock 2.4 Kernel
and our newer 2.6 kernels have
also been tested at 50K/s (although it did have keepalive turned on,
we copied the published coyote point tests)
Also it was obviously with very small packets and throughput was about
850MB/s on gigabit.. i.e. saturated.
Just had a look, and the results without keepavlive were only 14K/s:

Willy has had HaProxy running at 10Gbs (large packets), I find it hard
to believe LVS would be slower....
I'd be happy to send you some of our load balancers to test
performance (feel free to publish to the list.)
Where abouts are you based?
Not sure we have ever tested for max conns, but the 50K/s test was run
for 4mins giving @10,000,000 connections.
Any results are pretty relevant as we use almost stock kernels.
