Thanks Mikael - I have captured a wget with tcpdump, but Im not exactly sure what I should be looking for in wireshark....I see a LOT of "TCP segment of a reassembled PDU", a LOT of "Dup ACK's" and graph shows peaks of 25Mb...
In the other direction (another wget), I see very few (i.e. barely any) "TCP segment of a reassembled PDU", nor "Dup ACK's" > Date: Wed, 3 Apr 2013 06:50:50 +0200 > From: [email protected] > To: [email protected] > CC: [email protected] > Subject: RE: [c-nsp] Performance issue on link > > On Wed, 3 Apr 2013, CiscoNSP List wrote: > > > Im going to up a direct connection between the 2 linux boxes (by-passing > > the routers), and see if there is any improvement. > > The most productive thing for you to do instead of just blindly trying > things, is to actually do a tcpdump of your tcp traffic to a pcap file and > open this is wireshark and to a TCP stream analysis so you can actually > *see* what is going on. > > -- > Mikael Abrahamsson email: [email protected] _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
