Hi,
We are trying to use apache-tomcat 8.0.5 for our web application and have
encountered performance issue with respect to the page response time.
However, once the application is deployed in 8.0.5 we see a longer delay in
response time from the server for the login page itself. With older

The long response times experienced by your clients are more likely to

So AccessLogValve can execute once the Servlet is done writing. It may

OS might do some buffering. The outpu
Hi all,
Pardon me if this seems an ignorant question.
I’ve recently discovered the %D option in the tomcat
AccessLogValve to record response times on the “server side”.
I wanted to doublecheck an issue: does the user’s network
connection speed affect the time recorded by the AccessLogValve.
