#979 closed enhancement (fixed)

Use actual initial RTT value in streaming

<zab> the formulas are the same as tcp, but does tcp start off with some initial values?
<zab> I found them (on the same page I posted) tcp.initial_rto - 1 sec
<zab> no initial values for rtt or rttdev
<zab> our initial rto = 12 sec, initial rtt = 8 sec
<zab> rttdev = 4000
<zzz> see stats stream.con.initialRTT.{in,out}
<zzz> cant remember how in is calculated.
<zab> the calculation is the same one as tcp; the only difference is that tcp does not have an initial value for rtt and rttdev
<zzz> my stats are 3400 ms in, 4300 ms out
<zzz> either lowering initial RTT or using actual RTT sounds like a good idea - wherever the stats are set would be the place to call setRTT()
