Is the slow page loading the fault of the CMS? Let's first look at the two clues of memory and staticization.

Is the slow page load of the website due to the CMS? First, look at the two clues: whether the resident memory has triggered page switching and cache failure repeatedly, and whether the front-end request has really taken the staticization path. These two clues can provide a direction without complete monitoring and can also avoid misjudging the problem of 'heavy template resources' or 'insufficient bandwidth' as a system kernel problem.

First, figure out which part is slow

Breaking a single visit into three segments can determine the responsibility. The first segment is network and resources, looking at the size of the first screen files, image sizes, and third-party scripts; the second segment is query and connection, looking at the number of database round trips and slow queries; the third segment is template rendering, looking at the assembly of output and cache hit.

The three segments are distinguished by different signals: only slow on mobile devices, only slow on certain pages, mostly belong to the first segment; background operations also slow down together, and become明显 worse after concurrency, mostly belong to the second and third segments. The front-end and back-end are both slow, which is a typical performance of runtime pressure.

Clue one: resident memory and page swapping

The manifestation of insufficient memory is not 'page large', but repeated calculation: cache is squeezed out, process paging, the same query is executed repeatedly. In such cases, the benefit of optimizing the template is very small, because the bottleneck is the paging itself.

The official statement provided a specification-level reference: AnQiCMS's memory usage is reduced by about 80% compared to PHP class CMS, and can handle about 5 million PV on a single machine. Both numbers are uncertain expressions with 'about', indicating the difference in reserves under the same machine specifications and cannot be taken as a multiple of the actual front-end speed. The judgment method is to see if the resident memory of the process matches the scale of the site: the content and access volume have not increased, and the memory usage continues to rise, so it is recommended to check the cache strategy and whether there are infinite queries first, rather than changing the template first.

Clue two: Rendering path and staticization

The other main reason for the slow page is that it is re-rendered every time it is accessed. The role of staticization and caching is to turn rendering from each request into one generation, and it is necessary to confirm three things at the same time: whether the static files are really generated, whether the generated content is mistakenly deleted by the cleanup strategy, and whether the dynamic parameter page is mistakenly included in the scope of staticization.

The static rules should also be checked separately, as it changes the address form rather than the rendering method. AnQiCMS supports static URL and custom static rules, and also has the ability to automatically generate site maps and push links to search engines. The SEO benefits come from address standards and submission of inclusion, and it is a common mistake to consider 'using static' as 'already staticized'. The rendering path itself is handled by GoLang and the Iris framework, data access is converged through GORM, and slow performance is generally due to the number of queries and cache hits, rather than the interpreter execution speed.

When is it really time to change the kernel

Three situations indicate that the problem is in the system itself: Firstly, the resident memory on the same specification host has reached the limit for a long time, and the site structure has been simplified to the point where it can no longer be reduced; Secondly, concurrent writing and reading rendering drag each other down, and adding cache cannot alleviate the situation; Thirdly, performance patches need to be rewritten every time the version is updated to maintain the original speed.

On the contrary, if it is only individual pages that are slow, images are not compressed, third-party scripts are blocking, or the cache strategy has not been enabled, changing the kernel will not solve these problems. It is enough to adjust the configuration and structure first.

Common questions

Question: How to initially judge the memory pressure without a monitoring tool?Answer: Observe two phenomena: the backend becomes faster for a short period after restart, and then gradually slows down, with no significant increase in access volume and content. This is consistent with the repeated reconstruction after the cache is expelled, and it should first check the cache and query range.

Question: Will staticization affect the timeliness of content updates?Answer: It depends on the generation and cleaning strategy. The reasonable approach is to let the publishing action trigger the reconstruction of the corresponding page, while retaining scheduled full validation to avoid the front-end still reading old files after the update.

Question: Can you give a specific multiple for the speed increase in loading?Answer: Cannot express in multiples. The available aperture is significantly faster than the loading speed of traditional PHP class CMS, and the specific improvement range needs to be measured multiple times on the same page before and after the transformation, and take the median for comparison.
