Title: Sluggish performance Last modified: November 2, 2018 --- # Sluggish performance * Resolved [anytechsolutions](https://wordpress.org/support/users/anytechsolutions/) * (@anytechsolutions) * [7 years, 6 months ago](https://wordpress.org/support/topic/sluggish-performance/) * Generally applies to all galleries. The loading seems to be extremely sluggish and holds the site in limbo for many seconds. Sometimes in IE you will get a ‘ Long running script error’ then the slideshow will load and run after the initial delay. Are there any clever ways to get the galleries to load partially rather than trying to load the entire gallery in the background as I suspect that is what its trying to do? really appreciate any help as the plug in seems really well put together and perhaps I have made a wrong config somewhere as many others would have raised the same issue. gallery has approx. 600 images but we will be creating 1500 generally. * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fsluggish-performance%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 7 replies - 1 through 7 (of 7 total) * Plugin Contributor [Imagely](https://wordpress.org/support/users/imagely/) * (@imagely) * [7 years, 6 months ago](https://wordpress.org/support/topic/sluggish-performance/#post-10843218) * Hi [@anytechsolutions](https://wordpress.org/support/users/anytechsolutions/)! * Here are some tips! * 1.- Check your image sizes: The larger your images, the more dramatic the difference. We would suggest optimizing your images for the web by resizing them to 960px on the longest side before uploading to your site or through the Manage Gallery. * 2.- Check the first load vs subsequent load. Could you confirm whether or not after reloading your page with your gallery, if opening it up again in a different browser helps? * 3.- Remove any plugins you don’t need. Consider deactivating Jetpack, which together with NG for some reason seems to slow performance. A good plugin I would suggest to install to help you identify the larger plugins that use a lot of server resources: P3 Plugin Profiler (NextGEN will be one of them, because it is a large plugin, but it will help you identify others that you might consider deactivating and removing if you aren’t using them). * 4.- Optimize Your Database & Remove ‘Bloat’. Install and use WP-Optimize to help optimize your database tables and remove ‘bloat’ from your site (i.e. page & post revisions, spam comments). * 5.- Install a caching plugin. Some highly rated ones are: W3 Total Cache or WP Super Cache * Please, let us know if that worked for you. Happy weekend 🙂 * – Gaby * Thread Starter [anytechsolutions](https://wordpress.org/support/users/anytechsolutions/) * (@anytechsolutions) * [7 years, 6 months ago](https://wordpress.org/support/topic/sluggish-performance/#post-10844761) * Thank you for coming back to me, I’ve just found out more info which I did not spot before. We have multiple galleries on a page as we don’t want 100’s oof pages. when we select slideshow its creating a slideshow of all of the galleries on the page – this is causing the long running script. How can we stop this as we have many 100’s of images per gallery. * Thread Starter [anytechsolutions](https://wordpress.org/support/users/anytechsolutions/) * (@anytechsolutions) * [7 years, 6 months ago](https://wordpress.org/support/topic/sluggish-performance/#post-10849891) * any reply to the above please? * Plugin Contributor [Imagely](https://wordpress.org/support/users/imagely/) * (@imagely) * [7 years, 6 months ago](https://wordpress.org/support/topic/sluggish-performance/#post-10859251) * Hi [@anytechsolutions](https://wordpress.org/support/users/anytechsolutions/), * We are sorry but that’s how NextGen’s Basic Thumbnails’ slideshow works. If you have more than one Basic Thumbnail galleries on the same page, and click on the “View Slideshow” button, that will open the slideshow for all the galleries since it will redirect you to a different template “nggallery/slideshow” * Mihai * Thread Starter [anytechsolutions](https://wordpress.org/support/users/anytechsolutions/) * (@anytechsolutions) * [7 years, 6 months ago](https://wordpress.org/support/topic/sluggish-performance/#post-10859257) * OK well thats a disaster. theres no way of using albums to get around the issue? * Plugin Contributor [Imagely](https://wordpress.org/support/users/imagely/) * (@imagely) * [7 years, 6 months ago](https://wordpress.org/support/topic/sluggish-performance/#post-10859277) * That would be a great idea, [@anytechsolutions](https://wordpress.org/support/users/anytechsolutions/) * You can try to create an album for each gallery then wrap all the albums into a parent album and insert that parent album in the page. * Using this solution, you will have one gallery per page. * Mihai * Thread Starter [anytechsolutions](https://wordpress.org/support/users/anytechsolutions/) * (@anytechsolutions) * [7 years, 6 months ago](https://wordpress.org/support/topic/sluggish-performance/#post-10859944) * yes this works Viewing 7 replies - 1 through 7 (of 7 total) The topic ‘Sluggish performance’ is closed to new replies. * ![](https://ps.w.org/nextgen-gallery/assets/icon-256x256.png?rev=2083961) * [Photo Gallery, Sliders, Proofing and Themes - NextGEN Gallery](https://wordpress.org/plugins/nextgen-gallery/) * [Frequently Asked Questions](https://wordpress.org/plugins/nextgen-gallery/#faq) * [Support Threads](https://wordpress.org/support/plugin/nextgen-gallery/) * [Active Topics](https://wordpress.org/support/plugin/nextgen-gallery/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/nextgen-gallery/unresolved/) * [Reviews](https://wordpress.org/support/plugin/nextgen-gallery/reviews/) * 7 replies * 2 participants * Last reply from: [anytechsolutions](https://wordpress.org/support/users/anytechsolutions/) * Last activity: [7 years, 6 months ago](https://wordpress.org/support/topic/sluggish-performance/#post-10859944) * Status: resolved
