我们的团队有一个使用JRuby开发的Web应用程序，并在Tomcat 7.0.42 + Oracle JVM 1.8.0.51上运行。应用程序有一个主包装器servlet，servlet充当代理，将请求路由到处理它们的JRuby脚本
现在我们遇到了一个并发问题，即Tomcat连接器执行线程正在等待，并且只有1-2个线程在大多数时间都在工作。下面是本机线程堆栈显示问题线程正在等待的内容：

深入研究JVM代码后，我们找到了一些线索： 每次执行JRuby脚本时，它都会被解释并转换为类。要加载此类，将调用JVM JNI本机接口ClassLoader.defineClass1。 JVM的本机逻辑在定义类或动态调用方法（逻辑到JVM SystemDictionary cpp类）时需要独占锁定。
因此，我们正在考虑任何方法来缓解此性能问题，有没有什么方法可以调整JRuby以便它不会加载/卸载已翻译的Class对象？或者可以建议任何其他调整方法？
