I have switched from using the App Version to the OS Version, but with running Async test and throwing timers around the inserting of 100k files for 3 minutes, 10 mb. files for 3 minutes. I am not seeing any improvement from switching to using the OS driver dll. Why does is not appear to be any faster?

It was mentioned before (in one of your previous forum posts) that OS edition will not be faster. OS edition serves the other purpose - to make it possible for multiple applications access the storage concurrently via regular OS APIs. In most cases OS edition will be slower than Application edition.

I don't know what the Async test is, but it sounds like a multi-threading test. I think its important to note that SolFS is thread safe but based on my testing it does not scale with multiple threads. This can be the cause of your Async test not performing as expected.

Correct me if I am wrong.

SolFS is multithreaded and performs tasks in different threads in parallel. However there exist global objects (like a list of pages) which must be locked when the operation is performed on them. So it's not exactly clear, what you mean by "does not scale with multiple threads".
