NOTE: Use Browserscope instead!
UA Profiler is no longer supported. It has grown into the larger, open sourced project called Browserscope.
This is an archive version for historical purposes.
You'll be sent to the next test automatically. You can go there manually by clicking here.
This page tries to find the maximum number of connections a browser will open.
It does this by opening two images from each of 30 different hostnames ([1-30].cuzillion.com).
Each image takes 9 seconds to load.
The most connections that can be measured is 60 (2 images x 30 hostnames).
Therefore, browsers that support more than 60 open connections will be shown as just 60.
