No performance impact.

Unless, of course someone abuses the ports and connects a switch or a hub to two of them. In that case your whole network will probably melt down.

I would advise you to consider very carefully whether, and why, you want to disable your Spanning Tree protection.

Using it on a per port basis basically shuts off spanning tree , we learned that the hard way when we had a whole site melt down when someone looped 2 ports together on a access switch and we had bpdu filter on the user ports , your best bet is to use "either bpduguard or bpdufilter at the global level . I would do some reading as we also had some misunderstanding on how this works , it works differently at the global level versus on the port level .
