About Disabling Image Optimization

    Hi,

    I am currently using the Image Optimization features in the Litespeed Cache plugin. On my site, Optimize Original Images and Generate WebP are both enabled, and all of my existing images have already been processed by these features.

    I am now considering turning these settings OFF. What will happen to my existing images?

    1. For an image that has already been compressed from 500KB down to 100KB, if I turn the optimization feature OFF, will the image file on my server remain at 100KB? Or will it automatically revert back to the original, unoptimized 500KB version?
    2. What happens to all the .webp files that have already been created? Will they be deleted from my server?
    3. If the .webp files remain, will my website stop serving the existing .webp versions to visitors?
    4. What will happen to the status information in the Media Library (like “Orig saved 17%”)? Will this data disappear or change?
    5. Is turning these features off a safe and reversible action? If I turn them back on later, will everything return to normal without issues?

    My main concern is to ensure that my existing library of optimized images will not be broken or lost.

    Thanks,

    @gale13 not sure why would you disable Image Optimization.
    Is something speed related? or why?
    Please create a report ID, from LSC => Toolbox => Report => click on “Send to Litespeed”. Then share the ID generated.

    My report number is: VCAPXHKQ

    My issue is with high server CPU usage (100% CPU spikes), not website speed. These spikes often happen when Litespeed’s background image optimization is running at the same time as other heavy tasks (like me editing posts in the WordPress admin).

    I want like to temporarily disable the features as a troubleshooting step, to see if it helps reduce the overall load. I also plan to upload the webp imgae to the site.

    1. already optimized images will stay as it is , unless you manually proceed to destory and restore original images.
    2. same as 1
    3. you need to set “auto request corn ” to off , and keep “webp replacement”
    4. it will stay as it is , unless you destory and restore to original
    5. yes , if you do 3) , then you just need set it on again , then it will proceed to opitmize image from last one it optimized until your newest images. if you completely disable , destory optimized data and restore to original back , then all optimized images and records are lost , you need to start it from scratch again

    Thanks for your help. I have another issue. I’m experiencing extremely long execution times for wp-cron.php on my website, sometimes over 100 seconds. Using the WP Crontrol plugin, I see multiple LiteSpeed tasks (like litespeed_task_css, litespeed_task_ucss, litespeed_task_lqip) are still being scheduled to run every minute. I’ve already created the crob job twice/hour, the next run is right, but the schedule is not (the picture https://postimg.cc/7JVn0xTT). How can I fix this?

    HI again,

    I’m having a big problem with the Page Optimization features on my site, happybakingdays.com. When I have them on, my site becomes unusably slow. Here’s what I’ve figured out:

    • With LiteSpeed fully ON: My pages take over 12 seconds to load. The server waiting time (TTFB) is a massive 8+ seconds.
    • When I deactivate the LiteSpeed plugin: The page load time drops to around 4 seconds, and the TTFB is a healthy 1 second.

    How can I set it up so it actually makes my site faster instead of slower? I still deactivate the plugin at the moment.

    for wp-cron, our task should all be async , by that saying , the wp-cron will just trigger it , then do whatever else it has to do , you can try manually execute these tasks in your screenshot , you should see them finished like instant in front, and there will be a background admin-ajax.php request if there is any files needs to be pulled back

    for your long loading time, please try disable localization and “add missing size” , these are 2 most likely options
