To make better use of CPU time, we can create a pool of NHRTs to process the data. By maintaining a pool of running threads, we have no thread startup and shutdown overhead when running.
为更好地利用CPU时间，我们可以创建一个nhrt池来处理数据，通过维护一个运行中线程的池，在运行的时候就不存在任何线程启动和停止开销了。
A thread pool offers a solution to both the problem of thread life-cycle overhead and the problem of resource thrashing.
线程池为线程生命周期开销问题和资源不足问题提供了解决方案。
Without file system caching, this overhead is mitigated by the fact that XML columns are buffered in the DB2 buffer pool and CLOB columns are not.
在没有文件系统缓存的情况下，xml列在db2缓冲池进行缓冲而clob列则不是，从而可降低开销。
