When I load a page with IE started manually, page loads in normal, typical time. When tested from the same machine with WPT Agent (urlBlaster) I get very long result. What is strane every response time for http request is multiple of 5s.
That’s really bizarre - can you capture a tcpdump and attach it (or look at it in wireshark)? My first guess would have been dummynet but it looks like you have that disabled by using the connectivity=LAN
The socket connect’s also look like they have the same 5 second issue so it looks like something about the network path or filtering is only impacting the WPT test.
The station has been moved to another LAN and problem disappeared so at the moment I cannot catch a packet capture. Traffic shaping is disabled on all my agents.
What is really strange to me is that problem occurs only when IE is started by urlBlast. After had been started manually everything is all right.
