FileSpeedTest Instructions


On launching FileSpeedTest, a report is given about the accuracy of data that can be gathered on the computer running it. FileSpeedTest uses the computer's processor clock to time events. Therefore, the theoretical maximum accuracy on a 1.0 GHz computer would be 1/1,000,000,000th of a second. However, because of the way different windows systems report this timing, the actual accuracy will be considerably less than this.

Testing With Existing Files

After launching FileSpeedTest, you have the choice of opening an existing file to use as a test or of creating a new random file. If you work with a particular size and type of file, you will get the most realistic results by opening one of your own. Files are opened as "Read-only", however it is best to work with a copy of any important files when running tests or experiments with new or modified systems.

Click the "Open" button to open (read) a file. You will notice immediately that the amount of time taken to open the file is logged for you. To may now click the "Save" button to test the time required for saving (writing).

Creating Files And File Options

There are two options available when creating files for testing. Compressible files are strongly affected by file compression algorithms used in file transfer. Non-compressible files are not. You can try one of each of these of the same size to see how effective the file compression, if any, in your network is. It is important to note that compression is not common on LANs, but will often be present over dial-up networks.

Changing Files

To open a different file for testing, or to create a new one of a different size or type, you must first clear any file already in memory. Do this by clicking the "Clear" button.

The Log And It's Tricks

A log is kept of each action and it's result. There are buttons for clearing the log, saving the log, and for opening a previous log.

Sometimes you may want to look at a file other than the log, such as a file you are using to test. The "Open Log" button actually just triggers a function that reads any file into the log window as text. This can be a lot easier than navigating out, changing the file extension, opening the file in Notepad, and remembering to change the extension back.
