As an experienced website operations expert, I fully understand your concern about website loading speed.In today's internet environment where user experience is paramount, even milliseconds of delay can affect user retention and conversion.AnQiCMS (AnQiCMS) is a modern content management system developed based on the Go programming language, which has high performance and high concurrency as its core goals from the very beginning.bannerListDoes the label affect the page loading speed when fetching banner data?This issue requires an in-depth exploration of both the system architecture and front-end resource loading mechanism of AnQiCMS.

The performance foundation of AnQiCMS

One of AnQiCMS's core strengths is its high-performance architecture built on the Go language.Go language is known for its excellent concurrency handling capability (implemented through Goroutines for asynchronous processing) and its low resource consumption.This means that AnQiCMS can respond at a very high efficiency when processing data requests on the server side, even when faced with a large number of concurrent accesses, it can maintain stability.In addition, the static cache mechanism and SEO optimization features built into AnQiCMS also further ensure the fast response and friendliness of the page.

Under such a high-performance framework,bannerListThe tag itself is a component of the AnQiCMS template system, and its efficiency in executing data queries and template rendering on the server side is quite high.It will quickly extract the predefined Banner data from the database and convert it into an HTML structure.The Go language template engine is optimized, and the conversion of this data to HTML is typically completed in milliseconds, making it difficult to become a bottleneck in page loading speed.

bannerListThe working principle and potential impact of tags

bannerListThe main responsibility of the label is to obtain the home page Banner data configured in the AnQiCMS background. When we use{% bannerList banners %}this kind of label, the system will execute the following steps:

  1. Data query:The background service will query the corresponding banner records from the database according to your configuration (such as group name)type, multi-site ID)siteIdand so on).
  2. Data assembly:The data queried, including the URL of the Banner image (Logo) and the link address (Link) and the description (Description) and the image alt text (AltThe content etc., will be encapsulated into an array object available for template iteration.
  3. Template rendering:The template engine will iterate over this array, and generate a series of HTML structures based on the HTML structure you define in the template.<img>and<a>Label, displaying Banner images, links, and other information on the page.

From this process,bannerListThe execution process of the label itself is quick and efficient.Why do we still feel that the Banner area loads slowly sometimes, which affects the overall page speed?The volume and loading method of Banner resources (especially images)as well as,Front-end JavaScript interaction logic.

The factors that truly affect page loading speed

When page loading speed is affectedbannerListWhen tags affect, it is usually these aspects that are in operation:

  1. Banner image file size and quantity:This is the most common and the most important factor.
    • Large-sized images:If the banner image you upload is too large (for example, an image file of several MB), the browser needs to download more data, which will significantly increase the page loading time, especially under mobile networks or poor network conditions.
    • Too many images:Even if a single image file is not large, if there are too many homepage banners (for example, loading ten or more high-resolution banners at once), it will cause the browser to initiate a large number of HTTP requests, occupy bandwidth resources, and may block the loading of other critical resources.
  2. Image not optimized:
    • Not compressed:Images uploaded without compression will retain a large amount of unnecessary metadata and pixel information, resulting in a high file size.
    • Inappropriate format:Using JPG or PNG instead of the more modern, more efficient WebP format will also waste bandwidth.AnQiCMS provides the function to enable WebP image format and automatically compress large images in the content settings, which is an important optimization point.
  3. Image loading strategy:
    • Not lazy loading:If all Banner images are requested immediately during the initial page load, even those that are not visible temporarily (such as non-first images in a carousel), it will consume bandwidth.
    • Unresponsive handling:Load the same high-resolution image on different devices (PC, tablet, mobile), causing mobile devices to download large images far beyond their display capabilities, resulting in waste.
  4. The execution of front-end JavaScript:
    • Many banner carousel effects depend on JavaScript libraries to be implemented.If these JavaScript files are large in size, or have poor execution efficiency, or even attempt to manipulate the DOM before the Banner image is fully loaded, it could lead to page rendering blockage or 'flicker' effects, thus giving the impression of slow loading visually.

OptimizationbannerListUsage, improve loading speed

To fully utilize the performance advantages of AnQiCMS, while ensuring the quick loading of the Banner area, we can optimize from the following aspects:

  1. Deeply optimize Banner image:
    • File compression:Before uploading the image, be sure to professionally compress it to ensure that the file size is minimized without significantly reducing the visual quality.
    • Use WebP format:Enable WebP image format in the "Content Settings" of AnQiCMS, and use the provided batch conversion tool to provide images in a more efficient WebP format, which can significantly reduce file size.
    • Adjust image size:Exact crop or scale the image according to the actual display size of the Banner on the page to avoid uploading excessively large images.
  2. Implement image lazy loading (Lazy Loading):
    • For the carousel banner, only the currently displayed banner needs to be loaded immediately.Other banners can be loaded lazily, only when the user scrolls to the visible area or is about to switch.bannerListThe tag itself does not provide directlylazyParameter, but you can modify the template by using a frontend JavaScript library (such as LazyLoad.js)<img>the label attribute (for example, change)srctodata-src（and process it in JavaScript to achieve this effect。）
  3. Control the number of banners：
    • Minimize the number of home page banners while meeting operational requirements.The homepage is the 'face' of the website, but too many banners may distract users' attention and unnecessarily increase the loading burden.
  4. Using AnQiCMS cache mechanism：
    • The default static cache of AnQiCMS can cache the entire HTML output of a page.This means that once the page has been visited, the generated Banner HTML structure (including the image URL) will also be cached.The subsequent access will be read directly from the cache, greatly reducing the server-side processing time.Make sure your cache configuration is reasonable and effective.
  5. Responsive image processing：
    • Consider using HTML5's<picture>tag orsrcsetattribute, based on the screen size and resolution of the user's device, to load different sizes of Banner images, to adapt to mobile devices and save bandwidth.

Through these optimization measures, you can ensurebannerListThe use of tags in AnQiCMS is not only efficient but also will not become a bottleneck of page loading speed, thereby providing users with a smoother and more pleasant browsing experience.

Frequently Asked Questions (FAQ)

1.Why is the loading speed of my Banner image not significantly improved after enabling WebP and automatic compression of large images in the 'Content Settings' of AnQiCMS backend?This may be because: a) New images uploaded after you enable these features will be processed.For images that have been uploaded previously, you need to use the 'Batch Re-generate Thumbnails' tool provided by AnQiCMS or a similar image processing tool to perform batch WebP conversion and compression operations on the existing images.Your Banner image may be inserted in the rich text area of the content editor. Such images sometimes require additional configuration or frontend scripts to fully comply with the global image processing rules of the backend.

2. In addition to image optimization,bannerListWhat parameters do the tags themselves have that can help me improve loading speed? bannerListLabels are mainly used for data acquisition and basic structure rendering, they do not directly control the loading behavior of the front-end (such as lazy loading). However, you cantypeParameters can be used to call different groups of Banners, which can help you fine-tune and control the Banners loaded on each page or area, avoiding the loading of unnecessary Banners.For example, load the "Main Carousel" group's Banner only on the homepage and not on other pages or display different groups' Banners.

3. If my Banner area has complex animation effects, will these animations affect the page loading speed?Yes, complex Banner animations usually rely on JavaScript and CSS.If the animation script file is large, the execution efficiency is not high, or the CSS animation is too complex, it may increase the page loading and rendering time, and even cause the page to freeze.deferorasyncProperty), to avoid blocking the rendering of the main page content.AnQiCMS's Go backend can quickly provide data, but the optimization of frontend rendering still needs to be completed through reasonable code practice.
