Subject How to log response time ?
Date Sun, 03 Nov 2013 05:23:51 GMT
Hello.

I'm currently using tomcat 7.0.28-4 on debian wheezy, along with APR
connector.

I'm having a slow response when accessing the webapp.

Based on google chrome's tool to inspect req/response's time, i found out
that it takes at around 1 second (around 400ms connecting, sending 1ms,
600ms waiting, receiving 1ms) for to successfully fetch my initial htmp
response, which is slow, considering the time needed is excluding the
additional resources files like css and js.

The returned html has 4.5kbytes only, not compressed.

   1. Content-Language:
   en
   2. Content-Type:
   text/html;charset=utf-8
   3. Date:
   Sun, 03 Nov 2013 05:06:19 GMT
   4. Server:
   myserver.com
   5. Transfer-Encoding:
   chunked

I tried turning on and off the compression, but doesnt have any effects.
Here's my connector config :
<Connector port="80"
        maxParameterCount="500"
        maxPostSize="250000"
        scheme="http"
        secure="false"
        protocol="org.apache.coyote.http11.Http11AprProtocol"

        connectionTimeout="20000"
        disableUploadTimeout="false"
        connectionUploadTimeout="300000"
        maxThreads="500"
        processorCache="500"

        URIEncoding="UTF-8"
        />

Now, the backend's processing (in my case, an mvc controller) logging shows
that it took 75ms, and the ui rendering took 25ms.

I would like to find out how long does it take for the connector to return
this response. Is it possible for me to log this information ?

I also thought that the connection could be a problem, but my inspection on
different websites, they all have very good response time even for html
response 10 times bigger than mine, and i'm sure that the response is not
cached (not 304 not modified).
