I havnt tried it yet. I wanted to know if it is any good. I have an <URL SNIPPED>seo and web development company and I am always looking for new ways to increase performance. I was reading that it actually allows you to see where your site is allocating its memory so you can address the bottleneck areas.
If anybody has used it already please let me know how it is. I am very anxious to give it a try myself.
