Database performance plummets once index tables don't fit in memory anymore, so scale up memory as far as possible to hold tables.
一旦索引表再也无法装入内存，数据库的性能就会直线下降，所以应该尽量升级内存，以便存放那些表。
The experiment demonstrates that the new index structure has better performance of searching and needs less main memory than the hashing table.
实验证明，此索引结构比传统的散列表结构有更优的查找性能和更高的内存利用率。
