Wordpress LScache Plugin: TTFB is very slow even with default config
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hi, I am using lite speed server with ls cache enable. When the cache is hit ttfb is good. But on the first try it is very very bad as compare to no cache plugin: without lscache plugin: 800 ms with ls cache plugin default setting: 4.2 seconds(almost tried 5-6 times) How to resolve this?? i have not even started the optimization process still it shows very bad result consistently?? Running vultr high freq server.

I copied the the .htaccess file that was created after the plugin is activated(nthing change just the default setting). Then i deactivated the plugin and replace the .htaccess manually(that i copied from before) and then manually turned on the lscache in the httpd_config.conf (setting enablecache to true) and volla now both the cache is working and ttfb is also like before. I believe there is definitely something wrong with the plugin it adds around 2-3 seconds on the first try . Please see to it i believe there might be some bug in the plugin. Also are there any command that i can use to purge without using the plugin?? Does the command like wp litespeed work without any plugin??

Best regards, Hi, No plugin is installed and only theme and elementor is active. Definelty plugin issue. No problem when cache set manually. Please do look into it. It is quite a problem if there is a bug. did you enable object cache ? No, object cache is disabled in the default config. Redis is runnig thoough in the background but since it is not integrated with wp so i dont think that is the problem. I can try and disable it completely?? yeah , please try that way , but I think not related please create a ticket by send mail to support at litespeedtech.com , we will investigate it further Sure i will create a ticket thanks.
