Hi there Dave! :)

I'd just like to start off by mentioning that I'm a huge fan of your work, and have been following your developments since ~2019 when I stumbled upon the post on Facebook where you cracked down on YITH Wishlist performing a check against the entire database to find out which products are included in the Wishlist & which aren't. So to that, and everything else you've worked on & progressed in the WP Community, I say thank you!

I've just noticed that in Version 4.63 of your Scalability Pro plugin you've added indexes to improve the speed of WP All Import once again, this time by a factor of ~9.9x! This has gotten me highly interested, and now I'm considering purchasing the WooCommerce Performance Pack to try this out along with the others that are bundled with it.

Though, as with all Wordpress Purchases, compatability is always the first question that needs to be asked. I'll list each plugin below - and the questions I have for each under the plugin itself.

1. Super Speedy Search:

I'd recently just installed Relevanssi, as it's the only Search Plugin that's mentioned as being compatible with my theme (Woodmart) and have seen mild performance gains, from I'd say 6-7s queries down to 2-3s which is decent but most importantly the search results returned are far more relevant than they were using the default search. Woodmart does have an AJAX search bar, which returns a thumbnail, price & title results in a dropdown before pressing enter. To give you an idea of how their search works, here's a short forum post of a user who implemented Relevenssi into the Woodmart theme's search bar before it was officially included as part of the theme: https://xtemos.com/forums/topic/relevansi-plugin-ajax-search-for-everyone/

Would Super Speedy Search be compatible with Woodmart in this way & how relevant would the search results be in comparison? Are there any weighting options for Title & Description? I'd prefer Title over Description.

2. Faster Woo Widgets

You recently added support for YITH Brands (awesome!) but I'd like to ask whether they show up only as a text filter, or if they also include a Thumbnail of the Brands Logo (as the original YITH widget does?)

I also noticed that you have added a Colour Selector to the Colours Attribute, although Woodmart also has this functionality built-in, and we've already spent a lot of time configuring those, and they also have the added bonus of being shown as a swatch on the single product page for variations. Is there anyway your FWW plugin could be routed to fetch the Colour Selectors already configured in Woodmart, or something similar? My name suggestion by the way - Intense Filters for WooCommerce ;)

3. Auto Infinite Scroll

The Infinite Scroll seems extremely slow on the Foundthru.com demo, and the first page on each archive seems to always return a page of results that either do not have any images, or the images do not load for some reason.

Another thing is that whilst the Infinite Scroll does retain your position when clicking a product & then clicking it back, it doesn't retain your position when you've scrolled down past a few sets of results & then refreshed the page (it'll then force you back to the top once the page has reloaded, whereas other Infinite Scrollers will atleast send you to /page2 but without any results from /page1 as you've mentioned)

Then, just as my personal preference, is there a possibility you could edit the "More" button which appears after every 3 pages to say "Load More" and include an icon of the Mouse Cursor, to make it more apparent?

4. Scalability Pro

The one I'm sure we've all been waiting for :D. I actually don't have many tweaks to point out with this one, as most of the work is done in the back & barely visible from the front, although I will say that currently the demo is really slow & not doing this plugin any justice. Besides that, I'd just like to ask whether the changes made by this plugin are fully reversible (incase of any conflicts) & what your thoughts are on whether WP All Import had to implement similar Indexes as you have in version 4.63 as part of their plugin itself, as well as if Woocommerce / Wordpress had to implement many of the SQL optimizations you've made with this plugin into their own core - as we will eventually reach a point where they can / will drop the backwards compatibility that's currently holding them back? Where does the future of your plugins & our $365 purchase lie when that becomes a reality?

Just for reference, I'm using a Dedicated Server with 64GB RAM, Running CentOS 7, Plesk + PHP 7.4, Litespeed Webserver & Litespeed Cache (I'd tried setting up Varnish for more than a year but could never quite get it right - I'm really sad about that, but Litespeed seems like a really good drop-in replacement to that so far.) with Cloudflare as my CDN.

With all that said, please let me know your thoughts, and whether you think it may actually be a better idea for us to just purchase Scalability Pro rather than the Bundle?

I've currently got a total of 20 000 products on the store with 1000 orders & 1000 users, these numbers will only grow in time but I'm working with a plugin that generates a specs tables based off of product attributes - currently very few of my products have any attributes what so ever (~200) but with this Plugin (https://www.welaunch.io/en/product/woocommerce-group-attributes/) I'll be adding approximately 20-40 attributes to every product & their filters to the archive pages - whilst at the same time I want to avoid a longstanding 4-year core performance issue in WooCommerce for stores with many products & attributes listed on their Github here: https://github.com/woocommerce/woocommerce/issues/20262

Once again, thanks Dave. Your work is much appreciated! :)
