Well, we were and are giving Comcast a shot for our new office's internet access. While I am personally averse to Comcast's service and reputation, their product offering of 8Mbps/1Mbps throughput with a static IP is too much to resist. That is, it would be if we were actually seeing that. We've only had our firewall up for 6 hours, and here are the speeds I am seeing to our server in Dallas:
------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 85.3 KByte (default) ------------------------------------------------------------ ------------------------------------------------------------ Client connecting to picasso.centresource.com, TCP port 5001 TCP window size: 16.0 KByte (default) ------------------------------------------------------------ [ 6] local 192.168.1.3 port 32820 connected with 1.2.3.4 port 5001 [ 6] 0.0-10.1 sec 216 KBytes 175 Kbits/sec [ 6] local 192.168.1.3 port 5001 connected with 1.2.3.4 port 60231 [ 6] 0.0-10.3 sec 1.41 MBytes 1.15 Mbits/sec
Yes, you read that right. Our throughput is 1.15M/175Kbps up/down. Worse than our ADSL was. I am hoping this is just a problem on Comcast's end and not just normal congestion during the day, or we will be quickly moving to a T1.
UPDATE: This update comes with my tail between my legs. Those speeds we were getting look almost exactly like ADSL speeds, huh? Maybe that's because .. I left bandwidth throttling on our firewall at 1.5M/256Kbps. Woops. We're getting around 4Mbps/1Mbps now.
