Wow the link in the thread you posted: http://frankdenneman.nl/2011/02/24/ip-hash-versus-lbt/ Is very helpful!
I just have to learn more about what is a vNetwork Distributed Switch vs. how I have it set up now. And also what is a dvUplink? Then how or if I should convert my current configuration to this if I see any real performance benefit.
See when the consultant originally did this installation, it was ESX 4.0. I've since updated it to ESX 4.1 Update 3. Also I found the original install documentation and it was actually in the fall of 2009 when this installation was put in.
It wasn't until recently when we purchased a second switch to put in the VMWare rack for redundancy that we started looking into this configuration deeper. Trying to decipher the config, understand it, realize if its optimal or if there's a better way to do things now that its a few years later.
