Hi ,
Check on the major changes on Tomcat 7 to Tomcat 9. (One of the major
change we initially spotted is the BIO connector used in Tomcat 7 for
connector setup was removed in Tomcat 9:
https://tomcat.apache.org/migration-9.html#BIO_connector_removed)
May I know the major difference on BIO connector and NIO connector ?
https://tomcat.apache.org/tomcat-8.0-doc/config/http.html#Connector_Comparison
Note also that the APR/native Connector has been deprecated and removed
in Tomcat 10.1.x onwards.
if NIO have better performance, where can I get the bench mark
comparison report ?
The raw performance difference for a single connection is marginal.
While all this is true, it's not relevant: Tomcat has dropped support
for the BIO connector, therefore the performance is irrelevant.
If you are looking for likely performance impacts on your own servers,
what you'll likely see is that CPU usage goes up a few percent (there is
some cost to maintaining non-blocking communication), throughput stays
about the same (your NIC's performance is what dominates performance,
here), and you can handle MANY more simultaneous connections than you
were able to before (like 2-3 orders of magnitude).
