Support » Plugin: FiboSearch - Ajax Search for WooCommerce » How to fix admin-ajax high CPU usage

  • Resolved impulsatumarketing


    Hi, good morning

    I need an optimization help for this plugin. I’ve benn using it together with another plugins that make use of ajax for working, such us ajax filters for woocommerce.

    The thing is that I’m disabling all those plugins because I have several messages with error 500.

    I’d like to maintain this plugin for our customers and the question is if there is any way of optimizing this plugin because I think it’s causing extremely high loading resoruces of the CPU.

    Any help would be much appreciated because I’m in the high peak of my online business these days due to Mother’s Day.

    Thank you

    It’s hard to solve it because FiboSearch Free uses a native WooCommerce search engine and every search request loads whole WordPress files with theme and plugins.

    That’s why we decided to create FiboSearch Pro that has a different search engine based on the inverted index data structure. The Pro engine works under the special SHORTINIT WordPress mode. This means that each search query doesn’t need to load unnecessary files including all plugins, themes, and a large part of the WordPress core files. This results in the search always being fast and light, no matter how many plugins you have or how your website is optimized (or not optimized).

    The second partially solution is caching all resource-consuming queries, but currently, we haven’t a cache system in FiboSearch Free. We plan to add it.

    So I recommend upgrading to FiboSearch Pro if your store plan to handle higher traffic.

    We described the difference between Pro and Free engine here –
