Java log4j RollingFileAppender性能

我需要大量日志以进行进一步分析，因此，当文件滚动时，整个流会停滞一段时间，执行如下操作：

有什么改进“滚动”性能的想法吗

-DLog4jContextSelector=org.apache.logging.log4j.core.async.AsyncLoggerContextSelector

这是一个高并发性问题，它按设计工作。文件系统（I/O）没有足够的性能

尝试获取资源时，synchronized会阻塞一些Java监视器

/**
 * Determines if a rollover should occur.
 * @param event The LogEvent.
 */
public synchronized void checkRollover(final LogEvent event) {
    if (triggeringPolicy.isTriggeringEvent(event)) {
        rollover();
    }
}

上面提到的解决方案是转向异步日志记录

使用一种新的方法。让我们在自己的时间内处理文件滚动。您当前的log4j配置是什么？

/**
 * Determines if a rollover should occur.
 * @param event The LogEvent.
 */
public synchronized void checkRollover(final LogEvent event) {
    if (triggeringPolicy.isTriggeringEvent(event)) {
        rollover();
    }
}
