How do I make Dropbox sync faster or control the bandwidth used?

Dropbox is smart about using bandwidth. It will only use as much as it can without interfering with your normal Internet usage.

Specifically, Dropbox automatically throttles itself to 75% of your maximum upload speed to prevent any noticeable slowdown in browsing. Downloads are performed at the fastest download speed available.

These settings are customizable. If you'd like to change Dropbox's bandwidth settings, follow these steps:

 On Windows XP

1. Right-click on the Dropbox icon from your system tray and choose Preferences... from the menu
   
   
   The Dropbox icon on the system tray
2. Click on Bandwidth
3. You can manually adjust the bandwidth settings by selecting the radio button next to Limit tounder the Download rate or Upload rate sections, and entering the rates you prefer in the fields provided. Rates are set in kilobytes per second. If you want the fastest rate possible, select the radio button next to Don't limit.
