Any plan to upgrade this for Zen Cart 1.3.9b since the two core files touched by this more are updated in 1.3.9b.

I checked QC 1.6 and it works on multi level categories. I can’t tell for sure but I think it’s because QueryCache tries to prefetch part of products_to_categories table and it does not fit in server memory. If You have test site with copy of the store and You can give temporary access to it to me I can check what is the problem and develop patch specific to Your site.

I am wondering if anybody else is having problem with their site when QC_ZEN_GET_CATEGORIES_PRODUCTS_LIST_PREFETCH is set to TRUE. It doesn’t work for us when we have category level greater than 2.

No, unfortunately there isn’t any switch. If You want to turn off query cache edit includes/auto_loaders/config.query_cache.php and comment the line:

$autoLoadConfig[0][] = array(‘autoType’=>’classInstantiate’,
‘className’=>’QueryCache’,
‘objectName’=>’queryCache’,
‘checkInstantiated’=>true);

Make also sure to turn off all switches in includes/extra_configuration/query_cache.php

Is there a way to ‘turn off’ Query Cache easily instead of deleting and re-installing files. Want to compare differences in performance with and w/o Query Cache.

Query Cache does not use file based caching and does not store anything in cache/ folder. I’m not quite sure but I think it’s impossible to limit Zen Carts own cache. There are other cache solutions for Zen Cart – do You use any of them?

How do I limit the size of the cache dir, it seems to be getting massive
