Currently, new releases and major sales will cause Steam to slow down significantly, due to the spike in traffic.
The new tweaks will add a larger bandwidth threshold and "Steam will be able to serve content from more locations to reach international users better, and all content will be sent via HTTP."
Furthermore, Steam will be tweaked so users do not have to download as much data. When an update is passed, you will only have to download the modified bits, not the full update.
Finally, the company says "users can also expect new client features, such as download scheduling and priorities, bandwidth throttling, and the ability to update a game while playing."
