Magento: how to debug “admin”?

Question

In whole I have two questions where one follows from other.

I tried to run magento under linux and windows. Under linux base configuration works perfect. Under windows - doesn't. Every page is loaded about 20-30 sec., especially in admin panel.

So here are two questions.

1) I'd appreciate if someone posts some links about magento optimization.

2) How to debug admin panel? (it is like profiler for frontend with:

Varien_Profiler::enable();
Mage::setIsDeveloperMode(true);
ini_set('display_errors', 1);

Answer 1

Magento is a big resource hog and some recommended actions are:

• Enabled magento caching
• Enabled APC
• MySQL Query caching
• GZip compression of html,css,js
