Resource hungry

  • Has useful features but I found it rather resource hungry. Had a support discussion via email but couldn’t resolve some issues with sliders containing a large number of slides (30+). Frontend seemed to work OK but the admin backend exhibited high CPU% in the browser (Safari) and reloading a page took more than 10 seconds. Made multiple changes to the (Debian) server configurations but the backend kept crashing (WP serious fault notification) when trying to export a large slider. Have never seen problems like this with any WP plugins and am certain that all hardware is up to spec.

    Hi @zescoupe,
    I’m sorry that you had bad experience with Smart Slider 3.

    Export slider [memory limit]: I haven’t seen your slider so I can not say anything specific about this issue. The error message that you got indicated that PHP used 268MB of the memory and the memory limit stopped the processing of the request. To be able to export sliders with the images in it, Smart Slider needs to read every image and compress it into a zip file. Reading files mean that they are stored in the memory -> Simple saying if you have 30 image and each of them are 10mb, then it requires 300mb of memory limit to read them (in this cause no other post processing counted, liked the zipping of files).

    Slide editing [Safari]: On the frontend you do not experience any slowdowns because you might have a cdn or the lazy loading is enabled in Smart slider 3. In the slide editor every slide is loaded, probably without CDN. If you have 200mb of images, then the browser needs to download and process all of those images which is very heavy for web. We will check to see if we can improve the editing process to skip downloading images for the non edited slides.
