Hi Stuart,
Toby asked me to try on my machine, and I see an even bigger
throughput disparity. I'm using his test app:
https://github.com/tobias/undertow-speed
In one shell I run 'mvn clean compile exec:java' and in another I run
'./bench-avg.sh' and I get this output:
jim@minty ~/apps/undertow-speed $ ./bench-avg.sh
Requests per second: 14717.03 [#/sec] (mean)
Requests per second: 14527.32 [#/sec] (mean)
Requests per second: 14288.32 [#/sec] (mean)
Requests per second: 14375.64 [#/sec] (mean)
Requests per second: 14653.08 [#/sec] (mean)
Average: 14512
Then I run 'mvn clean compile exec:java -Pbeta9' in the first shell
and re-run bench-avg.sh. I get this:
jim@minty ~/apps/undertow-speed $ ./bench-avg.sh
Requests per second: 24069.72 [#/sec] (mean)
Requests per second: 25002.35 [#/sec] (mean)
Requests per second: 24885.36 [#/sec] (mean)
Requests per second: 25261.30 [#/sec] (mean)
Requests per second: 24800.82 [#/sec] (mean)
Average: 24803.4
As you can see, quite a bit more than 7%, beta9 yields almost 70%
better throughput for me!
I set the option you suggested for 1.3.18 and I get slightly better numbers:
jim@minty ~/apps/undertow-speed $ ./bench-avg.sh
Requests per second: 15749.52 [#/sec] (mean)
Requests per second: 15309.83 [#/sec] (mean)
Requests per second: 15909.15 [#/sec] (mean)
Requests per second: 16228.10 [#/sec] (mean)
Requests per second: 16118.84 [#/sec] (mean)
Average: 15862.6
But nowhere close to beta9.
Can you clone his app and reproduce locally?
Thanks,
Jim

Can you re-run but with the following setting:
.setServerOption(UndertowOptions.NO_REQUEST_TIMEOUT, -1)
The default changed between these versions, so now idle connections will eventually be
timed out (otherwise browsers can hold connections for a very time long which was causing
people to have issues with FD exhaustion).
