I am looking at changing our company's asymmetrical Internet connection (Uverse) to a dedicated fiber 20x20 connection. Will this be enough?
I manage our company's network, which consists of 5 buildings connected by single-mode fiber with at most, 150 people "on" the Internet at any one time - certainly never more than this and most likely closer to 50 -100 at at any given time. Also, on our connection is an email server for about 300 accounts. As an average in the daytime, probably 150-200 connections at a time (mostly IMAP or Airsync). 1/2 of those will be local connections, not coming across the Internet.
Our Uverse connection is a 24/3 "Turbo". We typically get 14-18 down and 2-2.5 up. I've never seen it faster than 18 down or 2.5 up.
(Previously we had a dedicated T-1 which was rock solid but outgrew that as the number of people on our network grew.)
I've been solicited by a reseller through ACC
for a 10x10 or 20x20 dedicated connection from AT&T now which is roughly 4-6 times the cost of what we pay now.
My question is, knowing that it is a symmetrical, dedicated connection - will our users notice the difference? I would think email users on the outside would notice a big difference, but inside users not so much?
I know about tools like iperf but not sure how to use them in the context of a question like this.
