Have you ever been using your computer and wondered if you were really getting the bandwidth you were paying for? Well, you can easily find out your up and down speeds with this useful HTML5 web tool. SpeedOf.Me is a web site that can be used to determine those up and down data speeds, and it is done without installing any apps on your system, nor does it require Flash or Java.
The SpeedOf.Me site was created four years ago in December of 2011. In less than a minute this web page running locally in your browser will run a seven pass download test followed by a three pass upload test. This will give you a quick snapshot of the performance of your broadband connection.
Test file sizes for download passes increase with each pass until it takes longer than eight seconds to download the file. Test file sizes range from 128KB to 128MB, doubling the file size between passes. The test files are all contiguous files, similar to what you, as a user, would be doing. Test servers from which the test files are downloaded and uploaded are spread around the world.
While the test will work with any browser supporting HTML5, the SpeedOf.Me folks recommend Chrome, Firefox or Safari for the best results.
I found this to be a great took and have added it to my bookmarks for future use.
UPDATE – One of my colleagues from CapMac contacted me after reading my post. He had compared SpeedOf.Me to others web tools and found some variation in the results. I followed up with similar tests and also found different speeds being reported. My first guess is that the methods of measuring the upload/download speed differs between these tools. That said, here is a table of the tools I tried and the results. These tests were run from the same Mac Mini over a 10 minute period.
