How often to poll WuUpdate about webudp

[seemk]

I think it depends on the maximum latency you're willing to accept when polling for new data. Currently WebUDP is sending SCTP heartbeats with 4 second intervals. If you're using it in a game, once per frame should be good I guess.

Did a few tests, and here's what I came up with:

3 test runs with 1ms second intervals and 3 test runs with 10ms. They show an increase of min time using the greater interval running roundtrip_histogram.html

test 1, 10ms interval
roundtrip_histogram.html:84 max=34.34 ms
roundtrip_histogram.html:85 min=0.59 ms
roundtrip_histogram.html:86 completed=100%

test 2, 10ms interval
roundtrip_histogram.html:84 max=34.17 ms
roundtrip_histogram.html:85 min=0.54 ms
roundtrip_histogram.html:86 completed=100%

test 3, 10ms interval
roundtrip_histogram.html:84 max=39.05 ms
roundtrip_histogram.html:85 min=0.60 ms
roundtrip_histogram.html:86 completed=100%

test 1, 1ms interval
roundtrip_histogram.html:84 max=37.21 ms
roundtrip_histogram.html:85 min=0.33 ms
roundtrip_histogram.html:86 completed=100%

test 2, 1ms interval
roundtrip_histogram.html:84 max=32.77 ms
roundtrip_histogram.html:85 min=0.38 ms
roundtrip_histogram.html:86 completed=100%

test 3, 1ms interval
roundtrip_histogram.html:84 max=44.98 ms
roundtrip_histogram.html:85 min=0.34 ms
roundtrip_histogram.html:86 completed=100%

One interesting note is that is showed a noticeable performance improvement over the regular EchoServer

roundtrip_histogram.html:84 max=185.61 ms
roundtrip_histogram.html:85 min=0.34 ms

roundtrip_histogram.html:84 max=141.45 ms
roundtrip_histogram.html:85 min=0.36 ms
roundtrip_histogram.html:86 completed=82.45%

roundtrip_histogram.html:84 max=238.99 ms
roundtrip_histogram.html:85 min=1.36 ms
roundtrip_histogram.html:86 completed=47.55%
