![]() Lazy loading is critical not only for good performance, but also to deliver a good user experience. You can also use ImageKit’s website analyzer to identify if your website uses lazy loading or not, in addition other critical image-related optimizations on your page. The audit performed by this tool has a section dedicated for offscreen images. You can find out which images are a candidate for lazy loading and how many bytes you can save on the initial page load by using Google Lighthouse audit tool. We trigger the load for these images when they become visible. For images it usually translates to any image that is not visible to the user up front can be lazy loaded.Īs the user scrolls down the page, the image placeholders start coming into viewport (visible part of the webpage). The basic idea of lazy loading is simple - defer loading anything that is not needed right now. This will become more apparent as we explore lazy loading further. This reduction in bytes transferred from your delivery network reduces delivery costs. Thus, you reduce the total bytes delivered on the page., especially for users that bounce off the page or interact with only the top portion of the page. Image delivery, or delivery of any other asset, is usually charged on the basis of the number of bytes transferred.Īs mentioned earlier, with lazy loading, if the image is not visible, it never gets loaded. The second benefit for you is in terms of delivery costs. Hence, the page becomes usable much sooner as compared to one without lazy loading. This ensures that the device is able to download and process the remaining resources much faster. Lesser resource requests mean lesser bytes to download and lesser competition for the limited network bandwidth available to the user. With lazy loading, you are reducing the number of images that need to be loaded on the page initially. This is the most important one for you as a website administrator - better performance and load time. If the user never scrolls, an image that is not visible to the user never gets loaded. An image, not visible to the user when the page loads, is loaded later when the user scrolls and the image actually becomes visible. Lazy Loading defers the loading of an image that is not needed on the page immediately. If an image is not needed up front, load it later when it actually needs to be viewed. For example, in a single page application, if a JS file is not needed until later, it is best not to load it initially. The technique of lazy loading can be applied to almost all the resources on a page. Instead of loading these resources as soon as the page loads, which is what normally happens, the loading of these resources is put off till the moment the user actually needs to view them. Similarly, lazy loading defers the loading of resources on the page till they are actually needed. The word “lazy” in the English language is often attributed to the act of avoiding work as long as possible. Here is a quick video to help you understand better: These techniques help in improving performance, better utilization of the device’s resources, and reducing associated costs. Log out of your terminal and log back in or just reboot.Lazy Loading Images is a set of techniques in web and application development that defer the loading of images on a page to a later point in time - when those images are actually needed, instead of loading them up front. :~$ sudo wget -P /tmp :~$ sudo bash /tmp/initial.shĢ. Get and make the script executable and run it.Finally enter the security token shown to you during the installation.Use your WAN IP / Domain name to connect to the server, and also don’t forget to enter the username and password shown to you during the installation.In your router forward ports 9987 – UDP, 10011 – TCP, 30033 – TCP to your internal LAN IP that was shown to you during the installation. ![]() Wait for the script to finish, make sure to write down the: server admin, password and the security token when prompted.Run the setup script by typing the sudo password:.Login using username: teamspeak password: teamspeak.Import the OVA into VMware (PC & Linux users) or VirtualBox (Mac users).Now with Webmin and Teamspeak Server 64-bit 3.1.0 INSTRUCTIONS Here you go: Teamspeak VM Ubuntu 16.04 LTS The ServerQuery is listening on port 10011 (TCP) and file transfers will use port 30033 (TCP). Now we can expand our VM base even more! Per default, the Teamspeak 3 server creates a virtual voice server on port 9987 (UDP). It worked quite well, hence the idea to just make a virtual machine out of it. That made us want to give it a shot and try out how it ran on Ubuntu. Last week we came to think of that back in the days we where gaming, we had stuff like Ventrilo and Teamspeak to voice chat with each other. ![]()
