Our second hypothesis was that specifying the buffer pool size affects memory utilization differently at various user loads (Test Case #2).
我们的第二个假设是指定缓冲池大小对内存利用率的影响因用户负载不同而不同(测试案例 #2)。
If the pool size is not tuned correctly, many unused object instances can end up hanging around, using up memory without contributing value.
如果对象池大小没有正确调优,许多未使用的对象实例最终会被闲置,耗尽内存而不产生任何价值。
