Disable the automatic application of update scripts on each page request following cache clear. Use MageRun to apply the upgrades manually within a controlled step.

Example Magento1 install script with some explanation.

// I almost never use $installer = $this; instead I prefer to use the following
$installer = Mage::getResourceModel('catalog/setup', 'catalog_setup');
// This is just an example of instantiating the setup class in the script. Of
// course I choose the appropriate setup class and resource on a case by case basis.
// That way it is very visible what setup class is being used. It can also be
// switched within a single setup script, for example to add attributes to

Magento's Performance Profile
View gist:2974947
There's multiple reasons Magento's performance profile is different
than most "mid-2000s" LAMP stack frameworks and CMS systems.
1. SQL Bottleneck: Magento's functionality is implemented in such a
way that there's a large number of SQL queries on each page request.
Between the special EAV structure of product/category models, and a
general "model first" approach to development, you end up seeing a lot
of SQL queries.
2. "Classical" (Java/C#) style OOP. Magento uses a class heavy

Improve Magento Layout Cache Efficiency
View Update.php
* This rewrite modifies the caching behavior so that the layout cache key references a SHA1
* hash of the layout XML instead of the XML itself to avoid duplication. The layout XML must
* still be generated once for each layout key, but it will not be saved if the identical
* contents already exist, saving considerable cache backend storage.

Magento 2 Cache Cheat Sheet

Magento 2 Cache Cheat Sheet

This page lists what caches or directories you will need to clear to apply various types of changes. It is consolidated and adapted from the complete official documentation on directories and caches.

💁 If your development environment supports it, you are better off using Vinai's automatic cache cleaner. As of this writing, the primary reason why it might not work is if your code is hosted on a NFS share (common with Vagrant).
