Nope :|. I've increased somaxconn to 512 and tcp_max_syn_backlog to 2048, but
with one process, 1M requests, concurrency 500, I still get a bunch of
timeouts, and the longest transaction still takes most of the test (eg 32
seconds out of a test that takes 35).
Any other obvious possibilities?

Yep sorry it's this one.

Hmm...I haven't tuned anything (this is just my workstation, not a server).
/proc/sys/net/core/somaxconn 128
/proc/sys/net/ipv4/tcp_max_backlog doesn't exist
/proc/sys/net/ipv4/tcp_max_syn_backlog512
I guess those are pretty low for trying to thrash an echo server...any
recommendations?

OK, I've decided to go a bit easier on the stress tools ;), and limited
concurrency to 500, using siege. That's resulted in some useful data

Hi, again.
Actually, when I think more about it, this service needs to support SSL, so a
Layer 7 implementation is needed.Also, when I put the TCP applet under any
degree of stress (as little as 100 request with concurrency 10), it hangs? The

Hi Thrawn,
I tried these configs, and there doesn't seem to be much if any
difference. The tcp one might even be the slowest in my limited
virtualized tests, but only my a few milliseconds..

Hmm...I seem to be able to set up something in TCP mode, and it returns the
expected response via curl, but its performance is awful. I must be doing
something wrong?
Lua:

local buffer = txn.f:src()
txn.res:send("HTTP/1.0 200 OK
b.t.w. if sole purpose of the frontend is to echo the ip back to the client.
You should probably also check the 'use-service' applet syntax, i dont
know if that could be faster for your purpose.
Then another thing to check would be if you want to use the tcp or http
service mode. A TCP service c

OK, I've set this up locally, and tested it against PHP using ab.
HAProxy was consistently faster (99% within 1ms, vs 5-15ms for PHP), but at
request volumes over about 35000, with concurrency 1000, it consistently had a
small percentage of socket disconnections. PHP had timeouts - or very long
Thanks, Baptiste.
I've had a go at setting that up, but found an issue in the process: I can't
build HAProxy with Lua support unless I install the OpenSSL headers. Which I
don't have any particular interest in doing, since I don't need SSL support.I
notice that there was a patch in March to be a
