How Fast Is Roadrunner Cable Modem Service?
Found this DSL diss on the Time Warner Cable San Antonio website:

7 mbps is a nice bump in speed for the standard Roadrunner service I currently use. The results of a Roadrunner San Antonio Speedtest show 7 mbps to indeed be about the speed I’m getting downstream:

Now for the less good news. When the fine print clearly states up to 7 mbps one probably shouldn’t expect to get the top end of that range all the time on every site you visit. That’s fair. No real complaint there. Too many other factors beyond the service provider’s control can come into play.
But what kind of throughput can you expect to get from Roadrunner out on the open road where mileage may vary based on your driving conditions?
I can’t answer that definitively for you, but here’s what the results from a cross section of other broadband speed tests I ran using Roadrunner suggest I am getting:
From the About.com Speed Test:

–
From the CNET Bandwidth Meter:

–
From the Toast Performance Test:

–
From my own ftp test downloading a 24MB video file:

Speed got as high as 4.7+ mbps then hovered in the 4 – 4.5 range from there.
–
Those test results, though short of the 7 mbps mark, I thought were actually pretty decent. But with test results like this suggesting that I’m having a tough time getting the full 7 mbps out in the world, I wonder when it makes sense to upgrade to Roadrunner Premium, which now boasts up to 10 mbps downstream?
