Package org.bedework.util.servlet.io

Class PooledBuffers

java.lang.Object

org.bedework.util.jmx.ConfBase<PooledBuffersPropertiesImpl>

org.bedework.util.servlet.io.PooledBuffers

All Implemented Interfaces:

org.bedework.util.jmx.BaseMBean, org.bedework.util.jmx.ConfBaseMBean, org.bedework.util.logging.Logged, PooledBuffersMBean, PooledBuffersProperties

public class PooledBuffers
extends org.bedework.util.jmx.ConfBase<PooledBuffersPropertiesImpl>
implements PooledBuffersMBean

See if we can't manage buffers better than the standard java classes - at least for the specific use we have. We are generating a lot of output and causing a lot of expansion and copying.

This may result in a lot of JVM churn. See if a pool of buffers can improve matters.
