- Thread-topic: Reducing the Minimum Packet Retransmit Delay on MacOS X
Is the minimum packet retransmit delay on Mac OS X really a second? Is there
any way to lower that?
We have developed an application for MacOS X which sends large amounts of
data to a custom hardware device over the network. During testing with a
direct Ethernet connection, we are seeing the Mac drop packets, and it takes
1.0-1.3 seconds to retransmit.
The documentation, and the Darwin tcp source, suggest that the rexmit
timeout is calculated as RTT + 4*RTTVAR. Our RTT is typically
sub-millisecond, so this would be fine, if the minimum retransmit delay
wasn't so long.
Any help is greatly appreciated.
Regards,
David
