MSIX: Runtime file performance


Not an issue that should be dealt with yet, but eventually must be.


Packaged simple test app that sequentially reads a large file.

Native test: 13.5 seconds

MSIX: 46.1 seconds.

Thanks for the report tim. What build of windows are you on? Would love to get the app to repro here.



Program is a standalone exe (attached).  Drop it in a package & make a shortcut to it.  Also drop in a large file (I used a 7+GB admx file, but you can find your own).  Default options used on the tool (sequential from front to end), Browse to the file and hit the load button.
