zones to the west have negative ones. Again this nicely compares to length: the "meter" is the mother of all SI length units of measure (the original prototype is a
The following examples show how to set the size of allocated memory to 6 MB using various units: -Xms6291456 -Xms6144k -Xms6m If you do not set this option, then the initial size will be set as the sum of the sizes allocated for the old generation and the young generation. The ini...

"If you cannot measure it, you cannot improve it". 在日常开发中,我们对一些代码的调用或者工具的使用会存在多种选择方式,在不确定他们性能的时候,我们首先想要做的就是去测量它。大多数时候,我们会简单的采用多次计数的方式来测量,来看这个方法的总耗时。 但是,如果熟悉JVM类加载机制的话,应该知道JVM默认的执...

Integration Testing: JUnit can be used to test the integration of different units of code, such as multiple classes or multiple modules, to ensure that they work together as expected. Performance Testing: JUnit can be used to measure the performance of code, such as response time and memory ...
Metrics are uniquely defined by a name, a namespace, and one or more dimensions. Each data point has a timestamp and, optionally, a unit of measure. When you request statistics, the returned data stream is identified by namespace, metric name, and dimension. ...
* while the unit of time of the return value is a millisecond, * the granularity of the value depends on the underlying * operating system and may be larger. For example, many * operating systems measure time in units of tens of
