 AccessLogValve cannot log until the request is done. Done meaning
 that the Servlet is done writing its content.

There's also the issue that the servlet cannot complete until the client has 
finished sending all of its content for the request.  In the case of something 
large, such as a file upload, the timer could have started long before all the 
content was received.

Hello,

I'm sorry but... Does it mean that network connection speed effectively
affect the response time logged by the AccessLogValve ? Something is still
unclear for me, I'm afraid.

Regards,

Pierre

In a word yes, but only for large transfers.  If the servlet has to wait for 
more input from the client, that will count; if the output cannot be sent 
immediately due to congestion or the client not ACK'ing the transfers, that can 
also delay the servlet.  Whether or not such conditions could occur depend 
mostly on what and how much you're receiving and sending.
