Hello, Recently while installing a firewall for someone, I noticed that the firewall seemed to cause/exacerbate Internet performance issues. There were some issues even without the firewall, but the firewall definitely made the issues significantly worse.
Of course I used Wireshark to perform a whole bunch of captures but I could not figure out anything definitive. I did notice that when I had a "problem" connection which would exhibit erratic throughput (for example, an http download), that there seemed to be a fairly high number of duplicate acks/retransmissions/out of order packets - around 10%. My question is - for trying to monitor/isolate/troubleshoot network performance problems, are there any addition ways I can leverage Wireshark or use complimentary tools? What about simulation? Would anyone recommend something like this to help? If so, could you recommend a tool to use in concert with Wireshark? Thanks, --Jim _______________________________________________ Wireshark-users mailing list Wireshark-users@wireshark.org http://www.wireshark.org/mailman/listinfo/wireshark-users
