If the performance of your inserts is not as good as expected, it may be because there is "hidden" processing taking place.

如果insert的性能不像预期的那么好，则有可能是因为有“隐藏”的处理发生。

Performance is not always as expected, often due to inability of the impervious layer to accommodate settlements at foundations, settlements due to bad compaction, seismic events, etc.

经常由于防渗层不能适应坝基的沉降、碾压不好造成沉降、地震等等，实施起来并不总是如预期的一样。

As it would be expected from such a small utility, it doesn't eat up a lot of CPU and memory, so the overall performance of the computer is not affected.

因为这将被从这样一个小工具预期，它不会吃了大量的CPU和存储器，所以计算机的整体性能不受影响。
