Hello.

I was looking for some performance issues and I found one thing with the help of this plugin *Login to see link

My Head Hook wp_head have long execute time. Clean WP instalation with Kadence theme had about 150ms, but my production environment site had about 600ms.

Then i searched the reason. I found that Kadence add very long inline css stiles in production environment site in compare with clean instalation.

This would be ok if I use all those settings, but i dont. For example. I have set maybe 3 social links, but in inline styles are every one that customization offer. In clean instalation there are no this settings in inline style in head.

I found settings, that was made for test, but now is not in use too.

Than i found theme_mods_kadence-child in database has option_value with almost 50000 characters. I see that it is the serialized multidimensional array. In comare with clean instalation it is big difference. There are stored many settings that i dont use now. Many array keys are without value.

Then I switched from Kadence child theme with customization settings to Kadence theme without custamization settings. My loading times was shorter. LAPS plugin show that wp_head is execute faster.

OK I know. Customizations. But I suspect there left many settings in theme_mods_ that are not in use now. Execute this useless setiings makes bigger load to the CPU and longer execute time.

Please. Is there a way how to clean theme_mods_ from settings, that are not in use. I think this is theme bug that should by fix.

Regards

Michal
