Scale the PTO timer.  A value of `FAST_PTO_SCALE` follows the spec, a smaller
value does not, but produces more probes with the intent of ensuring lower
latency in the event of tail loss. A value of `FAST_PTO_SCALE/4` is quite
aggressive. Smaller values (other than zero) are not rejected, but could be
very wasteful. Values greater than `FAST_PTO_SCALE` delay probes and could
reduce performance. It should not be possible to increase the PTO timer by
too much based on the range of valid values, but a maximum value of 255 will
result in very poor performance.
Scaling PTO this way does not affect when persistent congestion is declared,
but may change how many retransmissions are sent before declaring persistent
congestion.
Scale the PTO timer . A value of ` FAST_PTO_SCALE ` follows the spec a smaller value does not but produces more probes with the intent of ensuring lower latency in the event of tail loss . A value of ` FAST_PTO_SCALE / 4 ` is quite aggressive . Smaller values ( other than zero ) are not rejected but could be very wasteful . Values greater than ` FAST_PTO_SCALE ` delay probes and could reduce performance . It should not be possible to increase the PTO timer by too much based on the range of valid values but a maximum value of 255 will result in very poor performance . Scaling PTO this way does not affect when persistent congestion is declared but may change how many retransmissions are sent before declaring persistent congestion .
