we use cloudflare. @EducatorWaji I don’t get it! the site doesn’t load after 23 min. plus the site size is more or less the same (only 500kb different) with or without the images. as [this](https://meta.discourse.org/t/topic-list-previews/41630/566) reply show. i’m more or less confused now! 😲 after disabling topic preview only avatars + js files remains. but which js file? no other js is active on homepage (rather than ga). ---

Tense not! Don’t take my inputs as any major thing to consider. What is that .js script loading from [cdn.mathjax.org](http://cdn.mathjax.org) doing?. And for your info, MathJax is closing down its CDN by this april 30th. Whatever file you are loading from from mathjax will not be available after april 30th ---

that’s the mathjs plugin: [https://meta.discourse.org/t/mathjax-plugin-supports-math-notation-using-latex/12826](https://meta.discourse.org/t/mathjax-plugin-supports-math-notation-using-latex/12826) nothing in the latest page though from this plugin. ---

Yes! No use of the MathJs plugin. But, it still loads it in every page. I guess the lower speed is directly linked with the huge number of parallel image downloads. Disabling images gives good speeds. ---

let me see if I got you correctly: do you mean even if I disable the topic list preview plugin, the site still loads all the images of the first few topics? asking since when I disable the plugin, no such a huge change happens in the page size as well as the speed. ---

For that, I may have to test it myself. I will test it myself and get back to you. But, what I meant was force disabling every possible images in the site(Including logo, avatars and etc) gave me a very smooth loading time in your discourse. Which in someway pointing to the fact that the slow loading speed has something related with images. Anyway, I will try it myself and will get back to you. ---

@angus I think there is a problem with topic list preview. When I disable the thumbnail at site setting, my transfer decreases about 500KB, But when I completely remove this plugin the transfer decreases 1.4MB, What is this plugin doing? Why the transfer decreases so much when I delete this plugin but the disabled thumbnail reduce the transfer just 500KB, I thought the transfer for this plugin is images but I understood the transfer is for unknown requests. ---

So my assumptions are pretty accurate! The plugin loads a lot images when topic list preview plugin is activated. Whatever I write below are my assumptions, feel free to reply and correct me If I am wrong. - The plugins pulls the first image from the topics even while it is disabled, unless the plugin in fully removed. - After you have removed the plugin, The discourse doesn’t load the first image from the topic anymore. Hence much less Kilo Bytes of data is loaded ---

Hi, I reached this thread looking for improving performance and found that [meta.discourse.org](http://meta.discourse.org) does have a huge payload too: 1 single JS file stands out with size 1.69MB ![image](https://global.discourse-cdn.com/meta/original/3X/9/e/9e4593c100805d0670452a9388f71d389f0c08b4.png) The same application js file is loaded on my discourse install too: ![image](https://global.discourse-cdn.com/meta/original/3X/1/3/1343585bd4785614765c10fb39629746be5a2550.png) I tried a fresh install of discourse with no extra plugins and this file is still there with same 1.69 MB size. Is there a way to reduce the size of this file, if we going by your recommendations to keep the page size below 1 MB? ---

Look more closely, the actual **transmitted size** is 238kb ![image](https://global.discourse-cdn.com/meta/original/3X/9/9/99bcb54280927bd4660d980297b6cff91cf0fd4b.jpg) ---
