Magento performance
The document discusses optimizing Magento performance by addressing common coding issues. It identifies five issues: 1) placing SQL queries inside loops, 2) loading the same model multiple times, 3) redundant dataset utilization, 4) calculating array sizes on each loop iteration, and 5) inefficient memory utilization. The document also notes that some operations are better handled with SQL instead of PHP code and that business logic should not be placed in PHTML files. It emphasizes optimizing critical code, thinking clearly, and planning ahead.
