An issue has been found, identified, and hopefully fixed regarding performance in some cases - including Root Explorer (finally succeeded in replicating the problem). It's currently in the hands of some users and the Root Explorer developers for testing.
I'm not sure whether it could be related to the Samba issue and/or issues with other apps, but if you have one of these problems be sure to re-check with the next updated version. (and comment here about if the problem is or isn't fixed).
EDIT #1: The Root Explorer guys claim the issue is fixed
EDIT #2: Other testers also report this issue should now be solved. Expect an update soon.

You misunderstand me when I say it works for me. I'm not denying there could be a problem with SuperSU, but as long as I cannot reproduce the issue, I cannot fix the issue.
That being said, obviously you are unhappy with SuperSU. I'd be happy to refund your (or anybody else who feels the same) purchase. If you find the transaction in Google Checkout/Wallet, there's an option to request a refund.

I don't comment much here, but don't make the mistake of thinking I'm not following or reading the thread.
