About a month ago, I complained<\/a> about Time Warner’s anemic upstream bandwidth cap on home cable modem service. \u00a0(512k! \u00a0Oh, the humanity!)<\/p>\n

Well, a phone call to Time Warner and $10 a month later, my cap has been increased to 2 Mb. \u00a0They call this their “Turbo” plan. \u00a0(Turbo == fast, right?)<\/p>\n

The\u00a0asymmetry of my speedtest result below is still laughable, but the improvement in upstream AND downstream performance is very <\/em>noticeable. \u00a0Now my uploads to Flickr don’t completely saturate the connection and more than one person can actually use the network without hosing everyone else.<\/p>\n

I still suspect that my upstream bandwidth puts a cap on the actual download performance I can achieve. \u00a0I haven’t been able to find a rule of thumb to calculate how much upstream bandwidth is required to support a 20+ Mb\/s download.<\/p>\n

Surely there is a relationship between data coming down the pipe and the acknowledgements (or other handshaking packets) that are sent back?<\/p>\n
