Unfortunately, this approach itself can become a performance bottleneck if the size of the data requested is considerably larger than the kernel buffer size.

不幸的是，如果所需数据量远大于内核缓冲区大小的话，这个方法本身可能成为一个性能瓶颈。

If the bottleneck around Big Data is to loosen, the way forward might be in simplifying the tools to analyze it, so moderately skilled business people can ask the questions they really need to ask, and to understand the answers they get in return.
