I am experiencing slow loading Category Pages using Magento 2.4.0. We have 27,000 products of which approximately 6,000 are for the Magento website. The other 21,000+ are for eBay and Amazon. Normal load time for a Category page with 5,000+ products is less than 2 seconds. Long load time for the same page can be 10+ seconds. I have found that I can make the Category Page load normally again if I reindex these six indexes and then clearing any Invalidated Cache files (usually Page Cache will be invalidated after a reindex).

  1. Category Products
  2. Product Categories
  3. Catalog Rule Product
  4. Product EAV
  5. Catalog Product Rule
  6. Product Price

I must check our website for slow loading Category Pages every couple of hours. I must reindex those 6 Product Indexes 3 or 4 times every day. I have not been able to find an error in the logs when this happens. And I have not been able to identify the cause. Any ideas will be greatly appreciated. The website is hillcountrycustomcycles.com. We push a lot of graphics so the first page will take a couple of seconds to load. But after the initial load, the site should load quickly.

  • Issue could be poisoned cache, try leave block cache disabled, don't reindex, problem still persists?

  • Thank you for the suggestion, I disabled the cache for Blocks HTML output. I will let you know the result. Dec 29, 2020 at 22:36
  • Here 12 days since issuing the command "php bin/magento cache:disable block_html" to disable the BLOCK_HTML cache we have had NO incidents of unusually slow loading Category Pages. I think that is a good workaround. Does Magento Development plan to do anything about this malfunction? Jan 10, 2021 at 18:06
