Understanding RAM and performance

Random Access Memory (RAM): Three little letters and a very large impact on system performance.

What is RAM anyway?

When you start a program, that file is retrieved from the hard drive. It’s then placed in RAM temporarily while you're working with that program. RAM is your digital “workspace.”

RAM and speed

The more RAM you have (and the faster that RAM!), the faster your programs will run. RAM is used up quickly if you’ve got lots of software installed—especially if many different apps fire up at once when you start up.

Don’t buy more RAM. Boost your available RAM:

Identify problem apps and uninstall them. Disable apps that start unnecessarily when you boot up. Get a trusted system optimizer/RAM cleaner (like the one below) to do it all for you

Summary

Empty cache Mac will free up more space on Mac, and make Mac runs faster. Move cache to trash folder from Mac library, and then clear the cache from trash bin, but if we want to empty cache on Mac permanently, use EelPhone Mac Master, scan out all cache on Mac, and select cache files we want to delete.

The cache is a buffer for data exchange. When the hardware wants to read data, it will search the required data from cache. If it is found, it will be executed directly. If can't, the hardware will turn to memory. Because the cache runs much faster than memory, the role of the cache is to help the Mac run faster.
Because the cache was stored on RAM, the file will still be sent to the hard disk for permanent storage after it is used up, if the hard disk is full, Mac will run slowly. It's better to clear up cache folder on Mac from time to time. Get the cache file from Mac library or use EelPhone Mac Master to empty cache on Mac permanently.
