Hi guys,
We’ve run into a performance issue with the VM category module override.
On a site with around 500 categories and 20.000 products, even on a very fast server, this part alone takes about 10–15 seconds to execute on the first load. After some debugging, it looks like most of the time is spent inside this helper file when building the category tree and product lists: plugins/system/vmuikitx_override/html_override/mod_virtuemart_category/helpers.php
When temporarily disabling this override, the page load time drops back to normal.
So it seems the category/product aggregation logic in the helper doesn’t scale very well with larger category trees.
Although Joomla’s cache helps to some extent, it gets cleared relatively often, and the performance hit is quite noticeable — customers have already reported slow page loads.
Is there a way to optimize how the product counts are calculated in this helper, especially for larger category trees?
Environment: Joomla 5 + VirtueMart 4.6.4
Thank you in advance
