If both the target utilization and allocation rate are high, the application can run out of memory, forcing the GC to run continuously and dropping the utilization to 0% in most cases.
如果目标利用率和分配率都很高，则应用程序可能耗尽内存，强迫GC连续地运行并且在多数情况下使利用率降低到0%。
Although high target utilization is desirable for optimal application throughput, the GC must be able to keep up with the application allocation rate.
虽然高目标的利用率对于实现最佳应用程序吞吐量很有帮助，但是GC必须能够跟上应用程序的分配率。
An even better indicator is the rate of GC, as it is still meaningful even if you're comparing logs that do not cover the same amount of time.
更好的性能指示器是GC的速率，因为即使您对不具备相同时间的日志进行比较，它仍然非常有意义。
