During the optimization project, it often begins to focus on time performance, such as codec MIPS or mcps. When the time performance can meet the requirements, we often add the size parameter for comparison, then we need to consider a variety of size. This performance parameter may be clearly described in the project requirements book, and there are more prepared data records in the test performance result or release note. See the following table:

This time, the old database has about 0.3 million records. I did this for the first time and didn't think too much about the efficiency. This was implemented with the help of a friend.
