On CF-Talk, there&apos;s been an ongoing thread about <a href="http://railo.ch/en/index.cfm">Railo&apos;s</a> blazing performance. <a href="http://railo.ch/en/index.cfm">Railo</a> has always been known for its blazing speed and I&apos;m glad people are finally taking notice. 
David Low posted an interesting <a href="http://david.low.me.uk/2007/06/25/another-cfml-speed-contest/">speed comparison between CF8 & Railo</a>. David&apos;s tests show Railo clearly outperforming CF8 and by a healthy margin.

This must&apos;ve really set some things in motion because <a href="http://www.adobe.com">Adobe</a> decided to run their own performance comparison. Adobe&apos;s Damon Cooper posted the following performance stats on CF-Talk today and I have to say I was impressed & surprised by CF8&apos;s results:


"OVERVIEW: In all load tests here, we see ColdFusion 8 outperform Railo
everytime.

Testing Scenarios:
All tests were run with 100 Virtual users on Windows 2003 Sp2 Server with dual 3.60GHz CPU&apos;s and 2GB RAM.

Because we do not support TomCat running on Beta virtualization software ( Apple Bootcamp ) the following tests were run on a fully supported server platform. 

The following tests mirror some of the tests that were posted on your blog.

Test 1. Simple CFM page outputting a string.<ul>
<li>CF 8: Requests per Second: 800.94
<li>Railo: Requests per Second: 721.22</ul>

Test 2: Simple MySQL query returning 241 records.<ul>
<li>CF 8: Requests per Second: 279.15
<li>Railo: Requests per Second: 187.22</ul>

Test 3: Simple page with 5 cfincludes:<ul>
<li>CF 8: Requests per Second: 633.33
<li>Railo: Requests per Second: 631.43</ul>

I&apos;m not sure why in your testing you are seeing CF 8 take one second longer for queries to MySQL. Railo ships with an older MySQL driver ( MySQL Connector/J 3.0.1 ). CF 8 ships with MySQL Connector 5.0.5. In our testing, CF 8 and the newer driver were substantially faster when running queries."

These results show that ColdFusion 8 outperforms Railo! That was a real stunner especially in light of David&apos;s results.

This looks like its going to turn into an interesting debate.
