Re: [jetty-users] Unexpected delay after each HTTP response
|
I would suggest trying the same scenario using two separate machines, and using wireshark instead of fiddler. If you could get a trace that indicates that there's a delay in returning the response, please open a ticket at
http://bugs.eclipse.org/ for RT | Jetty project and attach your configuration file(s) and the trace.

Hi,
I'm running Jetty 7.4.4.v20110707. Every time I place an HTTP request (using
an application I wrote, not a web browser) I am getting a 500 ms delay
between the time the servlet returns the response and the time the client
begins receiving any bytes. I spent a lot of time trying to figure out
whether the problem was in the client or server. In the end, I ended up
using Fidler HTTP proxy between the two and got the following:
ClientConnected: 16:34:40.486
ClientBeginRequest: 16:34:40.486
ClientDoneRequest: 16:34:40.486
Determine Gateway: 0ms
DNS Lookup: 0ms
TCP/IP Connect: 0ms
HTTPS Handshake: 0ms
ServerConnected: 16:34:40.486
FiddlerBeginRequest: 16:34:40.486
ServerGotRequest: 16:34:40.486
ServerBeginResponse: 16:34:40.986
ServerDoneResponse: 16:34:40.986
ClientBeginResponse: 16:34:40.986
ClientDoneResponse: 16:34:40.986
Overall Elapsed: 00:00:00.5000500
I also had debug logs in a Filter and it reported:
2011-08-23 16:34:40.487,TRACE,ConnectionFilter.doFilter,qtp8806446-17 start
HTTP/1.1 GET http://10.0.1.32/devices
2011-08-23 16:34:40.489,TRACE,ConnectionFilter.doFilter,qtp8806446-17 end
HTTP/1.1 GET http://10.0.1.32/devices
Notice how, from ConnectionFilter's point of view, the request ends at
40.489 but from Fiddler's point of view, the response begins at 40.986.
ConnectionFilter is the outer-most Filter running on my server so I assume
any delays past this point are coming from Jetty. I assume I have something
misconfigured. Any idea what it could be?
Thanks,
Gili
