Hi,
I am using tomcat 6 in my product. I am planning to upgrade to tomcat 8 as
tomcat is going to EoS in Dec-2016.
I have just taken the performance of Tomcat 8 and found the 70% less
performance compared to tomcat 6. See the below results Tomcat 6 is giving
167473.2/s whereas tomcat 8 is giving 100436.6/s
I have just compared with two standalone tomcat which is just hitting the
HelloWorld servlet available in example.
Kindly let me know what need to configure to boost the performance.
Following are my setup:
Java=Java 8
HttpClient=HttpClient4
Benchmark tool=jmeter
