The <Context> Element
reloadable: If set to true, causes Tomcat to check for class changes in the WEB-INF/classes/ and WEB-INF/lib directories. If these classes have changed, the application owning these classes will automatically be reloaded. This feature should only be used during development. This setting will cause severe performance degradation, and therefore should be set to false when in a production environment.
The HTTP Connector
bufferSize: Specifies the size, in bytes, of the buffer to be provided for use by input streams created by this connector. Increasing the buffer size can improve performance, at the expense of higher memory usage. The default value is 2048 bytes.
