at this moment my ltm is using 'High Speed'. when there are heavy packet loss, the retransmission timeout goes to 32 seconds, and sometimes goes to 64 seconds. And this causes a whole transaction takes more than 4 minutes to finish, which usually just needs 2 seconds.
Wondering if 'Scalable' will be better?
Can the maximum retransmission timeout be set to lower value?
Hi Szkwg,
first of all, thank you for this interesting post. If i may, i would like to ask some questions:
- what is the average RTT of your link? RTO is normally calculated by RTT measurements, see also http://www.ietf.org/rfc/rfc2988.txt
- are those retransmission you are seeing timeout based? I am asking as i would expect dupacks to arrive, causing fast retransmissions.
Would you be happy to share an example tcpdump here ?
To answer your initial question, i would recommend the wom-tcp-wan-optimized profile.
regards,
Christian
