WP7 IsolatedStorage speed improvement



If you remember some time ago I did some tests on the IsolatedStorage and the speed was not very impressive (it was 127 slower than the FileStream). In the new beta version there is a TREMENDOUS improvement. I rerun the old test in the new emulator and these are the results:

Dividing the two values 0.0632/1.1866=0.0532 which is almost the same with FileStream. At this point it does make sense implementing/porting a database engine on IsolatedStorage. Well done WP 7 Team on this aspect.

  1. I ran the SQLite for SP7 POC against the new beta version (with my edits made) and the speed of my query went from 150ms down to 7ms. Quite the improvement. I put the details here: http://diaryofacodemonkey.blogspot.com/2010/06/sqlite-for-wp7-proof-of-concept.html

  2. Send me the source code of the tests you are doing and the results to dan.ardelean@gmail.com. I've done some improvments to the library and want to see if I get better results compared to yours.

  3. @Dan, send me your app and I'll run on the prototype device and let you know the results.
