What if we increase the size of cache which is more than RAM?

As cache stores data temporary. So if the size of cache increased upto 1gb or more it will not stay as cache, it becomes RAM. Data is stored in ram temporary. So if cache isn’t used, when data is called by processor, ram will take time to fetch data to provide to the processor because of its wide size of 4gb or more.

How do I speed up disk cache?

Why is cache memory so high?

In the case of the cache on a hard drive, it’s faster because it’s in solid state memory, and not still on the rotating platters. In the case of the cache on a web site, it’s faster because the data has already been retrieved from the database (which, in some cases, could be located anywhere in the world).
