In this particular program, doing buffer handling in this way does not affect the executiontime significantly, and in some data sets, affects it negatively.
在这个程序中，以这种方式执行缓冲区处理并不会显著影响执行时间，而对于某些数据集，可能有消极影响。

However, the JIT compiler must also carefully balance the time it takes to compile a program because that time adds to the program's execution time.
然而，JIT编译器还必须注意抵消它编译程序消耗的时间，因为这些时间将延长程序的执行时间。

Because compilation happens at the same time as programexecution, the time it takes to compile the code is added to the program's running time.
