N2048 Stacking Slows down network

We have recently stacked 3 switches using the provided stacking cables and come to realize that our backups are taking double the time to complete when connected to the stack as opposed to a standalone switch both are in the same subnet and not crossing any firewalls... basically going sideways

ideas????

I thought stacking was to improve performance not hinder it

we also notice that thestack is one of our top talkers on that subnet

RE: N2048 Stacking Slows down network

Hi,

What version is the firmware on the stack? Is there a lot of data being transferred between stack members? It is possible to have more network traffic than the stacking cables can handle.

Thanks,

Im running 6.2.1.6 on all 3 switches

I do notice that the stack has a lot of spanning tree traffic

I would try updating the firmware,  Spanning-tree traffic could do it, the stacking ports can only handle so much traffic at once.

You might be better not having them stacked.
