Data latency issues

I need Tier 2 support to solve an issue related to data latency.  A generic "speed test" shows adequate download speeds, but that's not my issue.  With very minimal load on a fairly overpowered machine, viewing pricing data of one instrument, I can literally see the time marker lag.  I'm watching data stream into my machine. As it does, I can see the time stamp on each price.  During busy times in the market, this data streams in millisecond stamps.  So many will come across within one second of time.  However, when you watch the data on my machine you can see that there is a lag.  As you're watching that clock, you will see hesitations in the timing. Instead of seeing a rhythmic second-by-second progression, you will see it hesitate, then jump two, or many seconds.  What this means is that during busy times of market activity I will get data in chunks instead of a stream.  It is not tradable.  And that is my reason for having internet.  It is my business and livelihood.  This issue has come and gone in the past.  Recently however, it has been more apparent.  It also seems to be affecting loading times for websites (which I have been less concerned with).  Today the issue remained in place continuously.  It could be related to the server I'm being routed to/thru, but when I asked the "technical support" person I spoke with today which server I was being routed through she had no idea what I was talking about.  I'm happy to upgrade to a business account, or even the next speed, but speed isn't the issue.
