Note that the sequential nature of the tests represents a worst case scenario for WinFsp. The reason is that a single file system operation may require a roundtrip to the user mode file system and such a roundtrip requires two process context switches (i.e. address space and thread switches): one context switch to carry the file system request to the user mode file system and one context switch to carry the response back to the originating process. WinFsp performs better when multiple processes issue file system operations concurrently, because multiple requests are queued in its internal queues and multiple requests can be handled in a single context switch.
