没有分区，将当前数据放到可以处理的正确位置需要许多开销，这种开销是随着机器的增加呈指数（不是线性）增长的。

Without partitioning, much overhead is incurred from getting the current data to the right place for processing, and this overhead grows exponentially -- not linearly -- as more machines are added.

当仅有少数几个基因组时，这种方法相对而言还比较快速；但是随着基因组的个数以指数形式增长时，这种方法需要耗费更长的时间。

This is relatively fast when there are only a few genomes, but as they grow exponentially, the searches take much longer.
