I won!
Over at BlogInBlock, Kai ran a Travel mashup raffle, which I won by being the first person to respond.
The fact we are in the same time zone gave me the upper hand!

*WHY* is CF8 so quick?
answer: Cause the ColdFusion Development team did lots of work!
When I started hear about how fast CF8 was I asked my self the question "I wonder how much of this is to do with the fact that CF8 is running on Java 6?"
I decided to run a quick test.
With my CF8 deployed on my old Jrun setup, using JVM 1.4.2, I did the olde (worst) load test and looped over instantiating CFC lots of times.
Here is my code:
Bob.cfc
<cfcomponent output="false">
</cfcomponent>
</cfcomponent>
Bob.cfm
<cfset iCount = 10000>
<cfset tcOne = getTickCount()>
<cfloop from="1" to="#iCount#" index="iIndex">
<cfset oBob = createObject("component","bob")>
</cfloop>
<cfset tcTwo = getTickCount()>
<cfoutput>
<h2>Creating an object #iCount# times</h2>
<p>
Total: #tcTwo - tcOne# ms
</p>
<p>
Average #(tcTwo - tcOne) / iCount# ms
</p>
</cfoutput>
<cfset tcOne = getTickCount()>
<cfloop from="1" to="#iCount#" index="iIndex">
<cfset oBob = createObject("component","bob")>
</cfloop>
<cfset tcTwo = getTickCount()>
<cfoutput>
<h2>Creating an object #iCount# times</h2>
<p>
Total: #tcTwo - tcOne# ms
</p>
<p>
Average #(tcTwo - tcOne) / iCount# ms
</p>
</cfoutput>
CF7 Results:
Creating an object 10000 times Total: 28250 msAverage 2.825 ms
CF8 Results:
Creating an object 10000 times Total: 5890 msAverage 0.589 ms
So, while I suspect having a newer JVM to back up CF8 installs *helps* with speed, it looks to me that it's a lot more than the JVM making it go like a scorpion strapped to a large rocket! :-)
