There must be a greater difference. If I use lscache_runner UA for cache warmup with curl instead of crawler and if I request all cached pages again, the amount of headers is much smaller and I get status code 201 instead of 200.

No, I can't, sorry. After I didn't get this information from LiteSpeed paid support, because they also don't know it, I worked on it for some weeks to find it out. Now, I know what has to be done. I can't give you this knowledge because that's part of my business. I hope you understand this...

@NiteWave && @Andy Badwool You are both completely wrong. LiteSpeed has its own logic how to handle <esi:inline

If you don't have LiteSpeed Cache plugin installed nothing happends and everything is the same as before without LiteSpeed cache. But you should try LiteSpeed cache plugin for Wordpress. It provides you not only with a server side cache funktion and has a lot of unique functions to optimize your...

I don't kidding you! Why should I do that?! I only wanted to be safe don't tell you information you don't need, so please don't understand my reply wrong, okay? As I already told you, the information about how to use ESI as inline tag isn't public and is undocumented, but it works because I...

There are different ways to use ESI. <esi:include basically doesn't need <esi:inline, but if you want to use ESI inline you must combine <esi:inline and <esi:inlude. Have you already tried the ESI example at...

Before you are able to get what you want, you must understand basics about ESI and how LiteSpeed modifies (undocumented) ESI language. You find information about it at: https://www.litespeedtech.com/support/wiki/doku.php/litespeed_wiki:cache:no-plugin-advanced:esi-support.

To get PrestaShop run with LiteSpeed LScache you need ESI support, but Open LiteSpeed doesn't support ESI.

You can optimize Apache as most you can, but it will never be as fast as LiteSpeed. This is based on different architecture of both webservers. To understand the difference on an easy way read this: https://blog.litespeedtech.com/2018/04/16/difference-between-event-driven-and-process-based/...

Maybe you don't know it, but Litespeed isn't something miracle. Litespeed is only a webserver and if it is running on a shared hosting with many clients with low ressources LiteSpeed can't compensate a slow connection to database. But in comparison to Apache or any other webserver LiteSpeed is...

Does anybody know why Firefox always use HTTP/1.1 protocol instead of HTTP/2 and why this browser not always get ls_smartpush cookie if there are sources defined to be pushed?

Can anybody tell me what is the difference between lscache_runner UA and any other UA? Has this (crawler) UA special privileges? Michael

If you want to redirect one or more URLs, it works like Apache redirect configuration in .htaccess. https://httpd.apache.org/docs/2.4/rewrite/remapping.html

If you have access to terminal/cli you can compress images with jpegoptim, an image library that is availabale on most Linux distributions. https://vitux.com/optimize-jpeg-jpg-images-in-ubuntu-with-jpegoptim/ https://www.tecmint.com/optimize-and-compress-jpeg-or-png-batch-images-linux-commandline/

Okay, but you can also be helped with PrestaShop. :) PrestaShop has a build-in function that differentiate devices like desktop and mobile devices. This function may produce differently code for each kind device. If you use LScache you must define vary cache rules in .htaccess, so Lscache knows...

This forum doesn't take WordPress cache plugin related questions, please raise you question https://wordpress.org/support/plugin/litespeed-cache/

I don't know if I understand your need completely, but redirect permanent == 301 == redirect permanent, so your first configuraton is okay.

You don't need Redis or Memcache and will not improve page load. Improve your hosting for better performance and network connectivity and you will get a much better result. And of course remove ads. They are the main reason for your slow page load.

Preloading objects means preload static sources like fonts, css, javascript before these static are requested by html code. Also known as HTTP/2 Push: https://en.wikipedia.org/wiki/HTTP/2_Server_Push. LiteSpeed supports HTTP/2 Push, but the function to push sources must be developed for each...

TTFB of your page isn't bad, but could be better if you use better network connection at your hosting provider. Too many hops and too much packet loss force too much time for packet transfer. Search for WIN application "WinMTR" and you can ceck it by yourself. The less of the number of hops and...
