We are going to launch a new Magento website & need to know it's speed when it's delivered by the Developer...so, which is the best tool to evaluate the speed of the website ? Thanks
You will discover simple speed assessments, thorough assessments with simulated targeted visitors coming from world wide, and also multiple-site assessments intended for head-to-head comparisons. Some resources present strategies to boost any site’s performance. Thats things you can do to speed up your site: * Optimize CSS Delivery * Enable browser caching * Reduce server response time and so on.
Page loading time is undoubtedly an important part of any specific website’s user experience. Check out Pingdom Tool. It provides understandable as well as effective up-time and overall performance checking for your online store.
I really like the Pingdom page tool. It also breaks down everything. YSlow is also quite useful, and it breaks things down a bit further
http://tools.pingdom.com/fpt/ is an online tool that we use very often to find website loading time and performance analysis. But do not rely on its load speed especially when your server is located in US. Because most time they use US based servers to test and the speed may be different from your location if you located elsewhere. Google's tool is very useful as well.
Put a timer in your script that starts when a page is loaded and stops when the script ends. There are a number of ways you can do this. One way is to modify your code to get the microtime() at the start of the script (save it in a global variable), get the microtime() at the end of the script, subtract the start time from the end time and output it in an HTML comment in your site's footer. That will tell you how long it took your script to execute. You might be able to do this using PHP's auto_prepend and auto_append feature which will automatically execute before and after the main script runs. You could put your start and stop timers in prepended and appended files, but adding another file include will increase the total time of executing the script by a small amount. http://php.net/manual/en/ini.core.php#ini.auto-prepend-file http://davidwalsh.name/prepend-append-files-htaccess Keep in mind that the first load time will always be much longer than subsequent loads. So do not bench mark first load on freshly booted server or after a period with no loads. Also as mentioned, tools.pingdom.com is a good tool to use as well. However, that will vary depending on network conditions and not be an accurate indicator of how long your script takes to execute. But it will give you an idea.
