Search Unity

Everyone knows the internet is made up of a series of tubes.  Since Unity has such a strong internet component in the webplayer, nothing but the fastest of all tubes are acceptable to deliver Unity webplayers to you and your players.

To harness the power of these tubes, Unity Tech has begun working with a content delivery service called Akamai.  Akamai provides server mirrors with fast connections around the world in order to make sure your downloads are as speedy as possible.  They do this for lots of big, well-known companies that you can see on their web site:

Because this download service affects users globally, we’d like everyone to help us make sure there are no kinks in the system.  If you can spare a moment, we have two tests for you to run.

Test #1: Download the Unity 2.5.0 webplayer installer through Akamai:


Test #2: Auto-update from 2.1.0 to 2.5.0 using Akamai


  1. Download the 2.1.0 webplayer (not using the Akamai service)
    * For Mac:
    * For Windows:
  2. Install the 2.1.0 webplayer
  3. Restart your browser
  4. Visit this url to auto-update using Akamai:


Both test #1 and #2 should be blazing fast.  If you can, please leave a comment about where you’re located and your average download speed, we’d greatly appreciate it!

    I had torrent in the background and it got around 250kB/s total. It doesnt get much faster so it must be exelent.

  3. Akamai download was 2 – 3 times faster than the downloads that did not use it.

  4. Montreal, Canada
    Test #1: 2 seconds
    Test #2: 6 seconds
    PC Windows XP

  5. It downloaded so fast that I couldn’t even check my top speed, it was over 1mb/s and probably hitting my max download speed of 1.6mb/s.


  6. I’m in Texas. The download finished before I can click save. I’m at work though, and I wouldn’t be surprised if we have some Akamai servers here.

  7. About 400 Kilobytes per second on a 12mbit link here in Singapore. That’s really really good for here as the link speed means very little when it comes to download. So all in all blazingly fast in the S’pore.

    In sweden on 50Mb/s.

    Downloaded 2.5.0 webplayer in about 3 seconds on avarage, so somewhere around 10Mb/s.

  9. i have a 15KBps connection (to slow) but the download was not arroun 15K. it was 13.5 and 14kBps

    location: iran
    our nasty government limits the interent speed to 128kbps (16KBps) for home users and in this sensitive times it’s slower but i think this 1 or 2 k decrease is your problem.

  10. Really fast here in Brazil.

  11. got between 1.9MB and 2.7MB a second on both downloads.

    Both on Windows.

    Location: Bournemouth, UK.

  12. hong kong, around 540 kb/s, midnight. around the best speed for my connection.

    54 kbps here in the philippines. using a slow crappy connection though. its the best speed i get though so its fast. :) Windows machine

  14. First download took about 2 seconds at the most. I briefly saw 1.9MB a second flash up.

    The update might have taken a second or more longer but not enough to notice.

    Both on Mac
