Please avoid using that module in production. If possible switch to Magento 1.8 or if you are stick to Magento 1.7 fix the deadlock bugs in Mage_Sales_Model_Abstract and Mage_CatalogInventory_Model_Observer::reindexQuoteInventory. For any more questions please ask @SchumacherFM

Disclaimer

I am not claiming this will fix anything or improve the performance of your store. Use at your own risk.

This is not intended to be a long-term solution for stores with systemic issues. This is meant to help solve real-world problems with stores suffering from deadlocks while they work out their own hardware, plugin, customization, other issues.
