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。
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.
如果应用程序负载不足—即它没有足够的工作可做—，则GC的速率不可作为良好的性能指示器，因为如果没有工作可做，速率将会下降。
If an application is under-loaded - that is, if it doesn't have enough work to do - the rate of GC is not a great performance indicator because the rate will drop if no work is coming in.
图形指示器包括条形，条形的高度根据数据传递速率变化。
The graphic indicator includes a bar whose height varies in accordance with data transfer rates.
