Virtual Developer Workshop: Containerized Development with Docker
Microsoft News: A quick review In a nutshell, ReadyBoost allows Windows 7s SuperFetch cache management technology to use flash-based devices to maintain a copy of the disk cache. Once ReadyBoost is enabled, it essentially keeps tabs on hard disk operations and will only go into action reading and delivering files from its copy of the cache when doing so will boost performance.
For example, during sequential read operations, ReadyBoost will sit back and allow SuperFetch to use the cache on the hard disk since the hard disk can outperform a flash-based drives for these types of read operations. During nonsequential read operations, ReadyBoost will jump in and essentially redirect SuperFetch to use the cache on the flash-based drive since a flash-based drive can outperform a hard disk for these types of read operations.
ReadyBoost does NOT equal RAMAnd one more thing that I should point out; ReadyBoost does NOT equal RAM. Ive heard plenty of people comment Oh, I have 8GB of RAM in my system, I dont need ReadyBoost. Thats only for systems with 1GB of RAM. The truth of the matter is that ReadyBoost is about improving hard disk performance, not enhancing or adding RAM to the system.
So, again, even if you have 8GB or more of RAM, there are situations where ReadyBoost can make a big performance contribution. So dont write it off.
Once you understand how ReadyBoost works and have it configured on your system, youre obviously going to be looking for the promised performance gain. Unfortunately, ReadyBoost isnt like adding rocket to your system fuel and its not going to dramatically speed up every task that you regularly perform.
Microsoft update: To see ReadyBoost in action, youre going to have to keep tabs on it with Windows 7s Performance Monitor
