Effect of having a DNS suffix in the domain/workgroup settings?

I have no idea if this is causing any issues or not, but one of our 10 SQL servers is having performance issues. There are many things I can look for in perfmon, but one thing that stood out immediately is this.
All of our SQL servers are in the same workgroup. There is no domain or Windows DNS servers for various reasons.

My last question is:
