For the record, the acquire or create semaphore reference VI is not the fastest thing

Are you talking about the actual semaphore VIs in the palette? If so, the issue may be more closely related to leaking the refnums. All I/O handles in LV are shadowed so that aborting or completing will do the close/free operations. And if you leak, that is a lot of resources to shadow. If you probe the refnum and see a unique one each time, you definitely need to close it.
If it is the WPILib Get VIs, which is it you are commenting on.
