Over one second sampling periods, this showed that Opera was transferring data five times faster, with similar CPU utilisation. Performance Monitor results on the P4 indicated around 200,000 bytes received and sent (acknowledgement) for 400 x 70 or 28,000 data bytes. The 70 bytes will be transmitted in larger packets. High overheads can be expected on loading the 70 byte GIF icons and these appear to be considerably higher using Internet Explorer, compared with the other browsers used.

The slow laptop might be affected by a USB 1 WiFi connection but there is no apparent reason for the PC using Windows 2000. Similarly, 100 kB might be around 0.2 seconds.įour of the systems can load 1 MB files in 1.4 to 1.6 seconds and this is similar with different browsers. In this case, maximum broadband speed is claimed to be 8 Mbps, where speed of loading 1 MByte files might approach a minimum of 1.2 seconds, taking into account overheads. Overall worst case results are also shown. For broadband, they are all connected to Internet via the same router, the laptops via wifi. The following show best case results from a limited number of runs using various systems and browsers. Image loading times can vary considerably, particularly due to network loading. Also, the timer does not always start on the first load but normally does so on selecting Refresh. Note that the measured time starts after the page has started loading. To reload from Internet via Refresh, the image page can be renamed as mypage.php, instead of mypage.htm ( see Local Tests below), with the time added to the file name on the remote server.Įxample HTML to do it - "> - One problem is that multiple copies of the files can be cached with a different suffix - example gif1m.gif?1232202066 and gif1m.gif?1232364678. On resubmitting the image page address, or selecting Refresh, the images are likely to be loaded from the cache at high speed. When images are loaded, they are saved in the browser’s cache on the local PC disk, known as Temporary Internet Files with Internet Explorer. These are intended for use over broadband connections but others, with lower demands, are provided for testing via dial-up lines. A further test loads 400 different GIF icons, each sized approximately 70 Bytes. Format of these files are uncompressed BMP, 0.33M pixels occupying 1M Bytes of RAM, compressed GIF, 2.33M pixels using 2.33M Bytes and compressed JPG, 3.15M pixels at 9.45M Bytes. Three tests load and display image files each of around one million bytes.
The first version is started using a Run button, but the second starts on loading the page. The benchmark pages provide links to results on PCs, older computers and using various other programming languages. The newer version was produced to overcome problems encountered using Firefox and Linux.
Later varieties were written using the Java programming language, the first being produced in 1997. The Whetstone Benchmark, introduced in 1972, was the first general purpose benchmark that measured computer performance. It is not advisable to leave this as a permanent setting. Note that, as the benchmark loads files from the server, Java Control Panel Security might need a Medium setting to allow the programs to run. Details and links to the on-line versions are in Of particular note, tests show that Internet Explorer is much slower than Opera and Mozilla Firefox on loading lots of small icon images.īesides the Whetstone Benchmark and Image Loading Time Tests described here, my off-line and on-line Java Drawing Benchmarks are available. Image loading times can vary, depending on the system hardware, operating system and browser.
#Online benchmark computer series
This page provides access to the Java version of the Whetstone Benchmark and a series of tests that measure image loading times.
#Online benchmark computer download
Most measure download speeds and sometimes upload speeds, often from servers all over the world. There are lots of online benchmarks available and found on searching Internet. Online Benchmarks - Roy Longbottom's PC benchmark Collection
