10. about:cache
All the web pages you view via Chrome are cached in the memory. This in increases the loading time of web pages when you visit them again. The cache is an important treasure of information and media of all the pages you visited. Chrome doesn’t have an option for you to set it’s cache size, but if you’re on an old computer, using few MBs of RAM, it is recommended to empty this cache, every once in a while.
