Throttle your upload speed on the Starcraft 2 downloader to increase download speed.
Running NetLimiter on the Starcraft 2 downloader to increase download speed.
As I write this I have just begun downloading Starcraft 2 after purchasing the digital download copy off of battle.net. I don’t know about anyone else but when I buy a game, especially one as long-awaited as Starcraft, I am itching to load it up and start playing it straight away!
Anyway, I started the 6.99gb download about half an hour ago. To begin with, the SC2 downloader gave me an estimated time of about 4 hours, which is ok I guess. But a few minutes later I watched in horror as the estimated time increased, 6 hours, 8 hours and so on. I looked at the connection details and realised that the downloader uses peer-to-peer sharing and that my upload speed was now higher than my download speed!
Fortunately within the downloader there is an option to switch off peer-to-peer sharing and just use direct downloading. I tried that but the speed barely increased. A quick scan of a few forums put me on to a little piece of software called NetLimiter. After installing NetLimiter I was able to re-enable the peer-to-peer method of downloading and limit the upload speed (within NetLimiter) to around 30kbps which saw my download speed eventually increase to around 900kbps.
A few points to be aware of:
- Limiting your upload speed too drastically seems to also drag your download speed down as well, so don’t go cutting it back too much.
- Inside the preferences for the Starcraft 2 downloader there is an option to disable background download throttling which I would also suggest you set.
- NetLimiter runs as a 28-day trial. Should you need to use it past the trial period then it only costs $30USD for a single user license.
I’ll let you know how Starcraft goes!
Also if anyone has their own experiences, suggestions or comments please leave me a comment.
