java.lang.Object

org.agrona.agent.BufferAlignmentAgent

public class BufferAlignmentAgent
extends java.lang.Object

Unaligned accesses can be slower or even make the JVM crash on some architectures.

Using this agent will avoid such crashes, but it has a performance overhead and should only be used for testing and debugging
