Hello,

I was troubleshooting a webpage connection issue and got many "tcp retransmission" & "tcp out-of-order", and the actual connection was hang for over 100 seconds before the page could be shown. Below are some of the examples:

All packets are inbound and all packets are traced twice and so are not real retransmissions. Looks like you need to de-duplicate the trace using editcap -D to get rid of the false alarms.

Hi mrEEde,

Thanks for the reply, would check why there was only uni-directional traffic and revert.
