Still using VM 3.0.9 (Joomla 3.4.1, PHP 5.4.45, DB: 5.5.51-38.2) basically, because have been debugging since I installed it (..lol we're all tryin')

So, I have a menu plug-in called juxmegamenu (default settings)...not sure if it is the culprit.

To-date, I have been using a smallish subset of virtuemart categories.
Now, when I populate all my categories, getting ready for "go-live", there are currently ~50,000 entries in vm_product_categories (which I expected, products may be in many categories).

Now, it takes approximatey 10-15 seconds to load any page! - including the home page, without products! (so, it might be that juxmegamenu thing?). Best menu I could find and too late to go back right now, as, I am trying to go live! Seems linear, in that, the more product-categories, the slower it gets.

The SHOP menu only has a max of 2 deep and very straight-forward. I have double-checked the db and it is fast. All indexes are working fine.

When I delete the four (4) category tables, the site is lightning fast.
  delete from xo_virtuemart_product_categories;
  delete from xo_virtuemart_category_categories;
  delete from xo_virtuemart_categories_en_gb;
  delete from xo_virtuemart_categories;

I did a chrome dev tools timing and there are what appear to be excessively high idle times like 4 seconds 6-8 total... I looked at all the sql running it is fine (I am a db/sql guy and 'C' programmer.. this Php stuff weirds me out ;). I have no idea how to find out what this "show-stopping bottle-neck" is.. I need a tool like: --> this is the slow script because... sure ;)
Anyway, this seems like should be so easy to track, and maybe it is.. I hope. Could someone please shed some light on what possibly could be doing this?

regards,
Steve

I think the problem is the menu. How does the menu work? It maybe even enough just to cache it. You can enable the vmdebug and set vmTime to measure the time. FPScherer meant sometimes ago, VM works with a lot categories, but not the joomla menu.
I should fix your bug, please support the VirtueMart project and become a member

Thank-you Milbo for your reply.

The category (shop) menu is a 'JUX megamenu' module. Is there a way to cache the whole module? (have never cached anything manually before)

Yes, perhaps the menu is loading every page refresh, but, I wouldn't think the menu is bringing back much data.. a few k.
Not sure where the contention is..

As I inferred, I will upgrade versions as soon as I get my site running somewhere close to bug-free, but, thanks in the interim to point out my insecure versions preesh lol.

Have you checked Debug information already or not? If not, do it now. Enable Debug in global configuration and configure Debug plugin to show profiling and query information.

This appears to be the last query that ran before the 500 error: (the timing was okay but sure is ugly)

..just a response to upgrading (I do though very much need your help to find out why 15 seconds to load home page or category-product search..any page.. when number of product-catefories increase.. ugh.. please).

I would love to upgrade but have made many customizations, and although, I have kept track of them all, I still need to get the customizations/extensions working first. Then, I can upgrade, apply the mods, successfully, and release the awesome customizations to fellow Joomla and Virtuemart enthusiasts..

regards,
Steve

Well JHtml::getJSObject is deprecated. Use json_encode instead. was a reported bug in Joomla 3.4.1
JRequest is deprecated and JApplication is deprecated  were errors from Joomla 3 days.
 not sure about the others, but they are consequences/legacies of old versions, deprecated logging is much better handled in Joomla 3.6.5
