Update: Google Informations - Google Desktop 5.8 for Windows: Increased Performance

Google Desktop and measure the time spent on actions such as starting up, shutting down, searching, adding a gadget, adding a new document to the search index, and so forth. We then took a page from the Google Chrome playbook by running the performance tests automatically for every single change we made to the software, on dozens of machines each time so that an average of the time measurements from all of them would give us a reliable comparison against previous versions.

Next, we refined an option that helps us improve the product, with your agreement. To send us information about problems you might experience, you can opt in to our error reporting system. If you have opted in, the system will send us anonymous diagnostic information about such events as crashes. In the new version, we improved this system to also detect and report situations where our product could be making your computer slow to respond.

We've learned a lot from these two new sources of data. The performance measurement system enabled us to discover some seemingly small changes that had a major impact on performance. We've been able to immediately fix changes that decreased performance, and learn from changes that improved performance. For example:
  • We found a way to cut memory usage during startup by about 50%.
  • Shutdown now happens five times faster, and we were able to avoid a seemingly innocuous state that would have almost doubled startup time.
From automated error reports sent by our beta testers, we learned that while Google Desktop generally performs very well, certain types of usage and some interactions with 3rd party software can trigger problems. We've made dozens of improvements based on this data. Here are some examples of what we've been able to fix:
A few obscure cases where interaction with third party software could slow the computer down when certain types of files were being added...
