![]() Pages with a longer load time tend to have higher bounce rates and lower average time on page. The BBC found that for every extra second of page load time, 10% of users will leave. Anything longer than that doesn’t feel “instant.” Delays of one second are enough to interrupt a person’s thought process. People can detect delays as short as 1/10th of a second. Page speed is important to a visitor's experience. A slow page means that search engines crawl fewer pages with their crawl budget, which can negatively affect your indexing. Research from Moz has shown that Google may specifically measure time to first byte when it considers page speed. Google has suggested that site speed is one of the signals used by its algorithm to rank pages. Time to first byte, the number of milliseconds it takes for your browser to receive the first byte of information from your webserver. ![]() Page load time, or the time it takes to display the content on your page.Page speed is how fast content on your page loads. Should there be a mere two-second delay in your page speed, your bounce rate can increase by 103%. They create a better browsing experience for shoppers. Image optimization for web and mobile exists to make web pages load faster. Image optimization helps lower your webpage’s weight and is a core tenet of good ecommerce web design, which results in the following benefits: Improved website speed This can result in a negative impact on your website performance. Data from HTTP Archive reveals that unoptimized images make up, on average, 75% of a total webpage’s weight. Images are the largest contributor to overall page size, which makes pages slow to load. WEBP images)īy finding the balance between the three, you can reduce image size and improve website performance. The goal of image optimization is to create high-quality images with the lowest file size. And that they don’t hinder web performance. ![]() Image optimization means ensuring your images look flawless on desktop and mobile. That is, getting your product images and decorative images to rank on Google and other image search engines. = e.UserState.Image optimization is about reducing the file size of your images as much as possible, without sacrificing quality, so your page load times remain low. ![]() Try to update the ListView by using the progress percentage // as an index in the ListView items Go through each photo using indices for ( int i = 0 i " + ProgramName PhotoCollection col = (PhotoCollection)e.Argument Cast the argument object to PhotoCollection Create an instance that represents the running threadīackgroundWorker trd = sender as BackgroundWorker Private void worker_DoWork( object sender, DoWorkEventArgs e) Run the worker thread, taking photos as argument Do not try to execute the background worker if // he is already busy with work if (!worker.IsBusy) When the thread has completed its work, the method worker_RunWorkerCompleted() is called which casts the results back to PhotoCollection.Ĭopy Code private void UpdateListView_HeavyProcess() The method worker_DoWork() will run the heavy process, and each time trd.ReportProgress() is called inside worker_DoWork(), the method worker_ProgressChanged() is invoked which is allowed to update the GUI components. The method UpdateListView_HeavyProcess() starts the thread and feeds it its working argument. The BackgroundWorker could also pre-generate thumbnails, and the ListView could be replaced with a “Large Icon” view like you can see in Windows XP or later. This software can be extended further into a resizing program, renamer, organizer, or whatever you would want to do to a collection of photos. The PhotoCollection can be exported into an XML file, and imported back from an XML file, using the class XmlParser. Each photo has a FileInfo instance and some added properties. When photos are added, they are stored in an object named PhotoCollection, that inherits from List. After inserting the image names to a ListView, a collection object is passed to the BackgroundWorker that scans each image and reports the progress back and displays it on a ProgressBar. The user has the option to select a folder or select some specific images. This article explains how a BackgroundWorker thread is run asynchronously to scan image dimensions. This article is an extended version of another article that I found very interesting, named BackgroundWorker Threads and Supporting Cancel, written by Andrew D.
