This is my first time posting and I'm fairly new to the Cisco world, so I apologize if this is a simple question.
I'm pretty familiar with the pros and cons of stacking, but I had a question that I could not find an answer too online.
I have (6) 3850 switches with 4x 1gig modules, all in the same IDF. Each one has a pair of 1 gig port-channeled connections back to my Nexus 5K cores. I was thinking about making these (6) 3850s a stack and port-channeling gig1/1/1 and 6/1/1 back to the cores (which are running VTP).
My question is this;
Would I have better throughput keeping these 6 switches independent (6 - 1gig port-channeled links) vs stacking the 6 switches (2 - 1gig port-channeled links)? It would seem like I would be over-provisioned.
I know it would be better to get (2) 2x10gig/2x1gig modules and run 10gig back to the cores, but I'm just curious what everyone's thoughts are.
Thanks for all the help.

Hi @kaetwo1
You currently have 6 switch traffic traveling through 6 different channels. If you do the stack, then you will have the 6 switch traffic traveling through 1 channel. In addition, each switch currently switches its own traffic, but to stack, the master switch will manage the switching of the 6 switches.
I think that if you have no administration problems or shortage of ports on your core switch, it is better to continue with your current topology.

Hello
I agree with @luis_cordova if you don't have much horizontal traffic and your not restricted in cabling racking etc then your current design would be applicable

I appreciate everyone's advice.
