Request to Query Cache users
2I promised to release new, more memory efficient version of Query Cache soon – unfortunately (or fortunately) it seems that PHP is quite good at managing memory and there’s not much to improve. Therefore version 1.7 of Query Cache will be delayed.
Request to Query Cache users:
If You use Query Cache and Your store is still slow and it’s not related to search script please contact me either on email, PM on Zen-Cart.com (data_digger) or by leaving comment. I’ll check Your site and try to make necessary changes in Query Cache v1.7 for You.

Is there any word on an update for 1.3.9d? I don’t seem to get any benefit to running the module.
I saw the updated version for 1.3.9c, but it didn’t cache any queries.

I’m going to release new version for newest version of Zen Cart (1.3.9g at the moment), but as most of my customers are still on 1.3.8/1.3.9a it’s not high on my priority list – sorry. Currently my primary focus is UTI and Randomized Tests.
