Using one/two clients with ab2 -c 250 -H 'Accept-Encoding: None' -n
100000000 http://testhost I can get:
Requests per second:    25360.45 [#/sec] (mean)
Connection Times (ms)
              min  mean[+/-sd] median   max
Connect:        0    6  94.8      3    9017
Processing:     0    4  16.7      3    5002
Waiting:        0    0  10.3      0    5002
Total:          0   10  96.3      6    9022
Percentage of the requests served within a certain time (ms)
  50%      6
  66%      7
  75%      8
  80%      8
  90%      9
  95%     10
  98%     11
  99%     13
 100%   9022 (longest request)

Maximum session rate is 49000 (exact value).

Also, I've found reason why SYN packets were lost. It looks like it
happened because of slow interrupt handling (same ksoftirq/0 at 100%),
ifconfig eth0 reports dropped packets. I've tried to set ethtool -g
eth0 rx 2040 and dropped packets are gone at least according to
ifconfig.

Also I've upgraded kernel from 2.6.38-r6 (gentoo) to 2.6.39-r3
(gentoo) - nothing changed. At all. haproxy version is 1.4.8.

Altering somaxconn also did change anything.

Only changing affinity of irq/haproxy is affecting system, maximum
rate changes from 25k to 49k. And that's it...

I'm including sysctl -a output, but I think all this happens because
of some troubles with bnx2 driver - I just don't see any explanation
why 70-80Mbs are saturating haproxy and irq handling (lost packets!).
I have an option to try 'High Performance 1000PT Intel Network Card'
could it be any better or I should try find solution for current
configuration?

My final task is to handle DDoS attacks with flexible and robust
filter available. Haproxy is already helping me to stay alive under
~8-10k DDoS bots (I'm using two servers and DNS RR in production), but
attackers are not sleeping and I'm expecting attacks to continue with
more bots. I bet they will stop at 20-25k bots. Such botnet will
generate approx. 500k session rate. and ~1Gbps bandwidth so I was
dreaming to handle it on this one server with two NIC's bonded giving
me 2Gbps for traffic:)
