III. Theme History

On Optimization History, you could overview Time to get log, the number of file in Theme Optimization and theme name.

Optimization history: load 5 latest logs sequentially from the upper to the bottom, and from the newest to the oldest log. If it's over 5 logs, it will jump to the next page.
All logs will be saved within 30 days from the beginning, logs will be cleared automatically after 30 days.

Special note:

If you have run all the optimize tool but your speed score on Google PageSpeed Insight can not increase much, that's because your current theme structure is having specially heavy elements that need a deeper investigation rather than an auto tool.
