Debugging (Resource) Model Instantiation

Follow each step manually and any bugs during (resource) model instantiation will become obvious.

Since many people find model and resource model instantiation to be one of the more challenging things in Magento 1, these are all the steps Magento does to resolve the factory name to the real PHP class name.

To debug, simply follow each step manually until you find a non-match. This works really well in my experience.
Less guessing, more and faster results.

In the examples I use a factory name of "example/thing".

Magento Scaling Hypotheses

Magento’s checkout throughput can increase to at least 8 times its current capacity and up to 26 times more in ideal conditions.

1. The current checkouts per hour limit for large, real-world Magento stores is 4,500
2. This limit cannot effectively be increased with more and/or better hardware
3. The improper type handling in Magento’s SQL code is the cause of the current limit
4. If one SQL query is fixed, large Magento stores can scale to a new, real-world limit of 120,000 checkouts per hour
5. For commodity hardware, this new limit might be 36,000 checkouts per hour
