Subject Performance Issue while upgrading from Embedded Tomcat 6 to Tomcat 7
Date Fri, 17 May 2013 10:51:07 GMT

Hi All,

I have upgraded my application from Embedded Tomcat 6 to Embedded Tomcat 7. With Tomcat 6,
I was getting around 70000 Transactions per sec with a simple HTTP service,which sets the
HTTPResponse and returns it.

Now with Tomcat 7,I am getting 54000 transactions per sec. Going through the web I figured
out that it may be due to Servlet 3.0 API. I have updated my web.xml so that Servlet API doesn't
scan the classes for annotations. This is how my web.xml looks like:

<web-app metadata-complete="true" xmlns="" 


Can anyone provide some other measures I can implement? 

I am using an HTTP Client to test my performnace.
