My wfie said last night that things seemed sluggish. Today its been a bit odd with sites seemingly taking a while to load. A speed test shows
I managed to get a Wireshark capture which I've put at http://www.tty.org.uk/bbc but apart from a couple of Out-of-Orders and a couple of re-transmissions I can't see anything glaringly wrong apart from the huge delay at the start (but I'm no Wireshark expert).

Thanks for the Wireshark Steve, if you ever link to them in future though, it's probably best to save the captures as .pcap files as it makes them much easier to read at this end.

33 seconds to load the front page at www.livejournal.com?
Something is very wrong... and again I got immediate DNS response then it just seemed to sit round waiting.
Now which pcap format from the Linux wireshark capture do I need to save it in?
