Keep tabs on ReadyBoost with Microsoft Windows 7's Performance Monitor


How to Help Your Business Become an AI Early Adopter

Microsoft News: A quick review In a nutshell, ReadyBoost allows Windows 7’s 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.

Furthermore, fast hard disks pushing 7200-RPM or higher will in many cases be able to perform some, but not all, nonsequential read operations faster than a flash-based drive. As such, ReadyBoost won’t provide as significant of a performance gain as it would if your hard disk is running 5400-RPM or lower, such as those typically found in laptops. However, even if you have a fast hard disk, there are situations where ReadyBoost can make a big performance contribution. So don’t write off ReadyBoost just yet

ReadyBoost does NOT equal RAMAnd one more thing that I should point out; ReadyBoost does NOT equal RAM. I’ve heard plenty of people comment “Oh, I have 8GB of RAM in my system, I don’t need ReadyBoost. That’s 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 don’t write it off.

Once you understand how ReadyBoost works and have it configured on your system, you’re obviously going to be looking for the promised performance gain. Unfortunately, ReadyBoost isn’t like adding rocket to your system fuel and it’s not going to dramatically speed up every task that you regularly perform.

Microsoft update: To see ReadyBoost in action, you’re going to have to keep tabs on it with Windows 7’s Performance Monitor

  • IDC estimates that more than 70% of organizations have a cloud-first application deployment strategy to align with digital transformation initiatives. As such, many organizations are transitioning to Microsoft Office 365 and utilizing public clouds such as Microsoft Azure. However, IT leaders are discovering that default data protection schemes are not as robust as they desire. As a result, many are turning to Veeam® to provide the necessary data management and protection policies demanded by the …

  • Why use NoSQL? Innovative companies like AT&T, GE, and PayPal have successfully transitioned from relational to NoSQL for their critical web, mobile, and IoT applications. By understanding where to introduce NoSQL, how to model and access the data, and how to manage and monitor a distributed database, you can do the same. This white paper explains the need for non-relational databases, describes advantages of NoSQL, and clarifies the important difference between SQL and NoSQL databases. We walk you …
