The default mode, performance is very low, without any optimization and support.

2) nio

If you want to run in this mode, directly modify the Connector node in server.xml and change the protocol to

After starting, it can take effect.

3) apr

Installation is the most difficult, but from the operating system level to solve the asynchronous IO problem, greatly improve performance.

Apr and native must be installed, and apr is supported by direct startup. The following changes are superfluous, only for you to expand your knowledge, but you still need to install apr and native

For example, modify the mode of nio and change protocol to org.apache.coyote.http11.Http11AprProtocol.
