Steam readies update to download system, just in (Valve) time

Steam is not known to be the most reliable when it comes to updating; this is particularly true during the launch of a high-profile game when network traffic is at a peak. One such of those times happened for the last week-or-so during Valve’s fairly epic summer sale. Valve has, as usual, promptly addressed the issue and will be rolling out this new system starting today with a new client update forthcoming to support this new infrastructure.
If other people are any indication: complain profusely while browsing more discounted bundles.
One method that the update will utilize to improve your downloading experience is to switch to the standard HTTP protocol for data transfers. There are two main benefits of HTTP: In the event that you are in a particularly nasty firewall environment, HTTP is more readily permitted than other ports for users with sane network administrators. The second benefit of HTTP is that data that protocol is potentially cached, thus if you and another user share some stretch of the internet between you and Valve, it is possible that you will not need to fetch the data all the way from Valve as the other request brought a copy of the data closer already. Besides HTTP, the other method of improving performance is the ability to perform differential synchronization. If a 2GB file is edited by 4KB, you will soon only need to receive the 4KB difference.
Valve, not being able to resist a troll, closed by teasing that DOTA 2 will be delivered using Steam’s new delivery system. They also claim that if you want to try out the new system, download a 1280x720 trailer from the Steam store because they already rolled out the new update to that part of the system. Let us know what you think in the comments.
