ColdFusion 8 is fast, really fast, and in the CFUnited keynote this morning I presented some actual numbers (all reported as requests per second, the higher the number the more load the server can handle):
- Structure manipulation: CF6.1=99, CF7=101, CF8=200. In other words, CF8 manipulated structures twice as fast as CF6 and 7.
- List manipulation: CF6.1=33.6, CF7=34.4, CF8=103.4. CF8 list manipulation is over three times faster than that of CF6 and 7.
- CFSWITCH/CFCASE: CF6.1=66.2, CF7=88.9, CF8=244.4. CF8 is three times faster than CF7.
- CFPARAM: CF6.1=8.9, CF7=9.6, CF8=341.4. Yep, thirty five times as fast!
- Date functions: CF6.1=230, CF7=251, CF8=1423. About six times faster in CF8.
- RegEx functions: CF6.1=390, CF7=392, CF8=987. Over double the speed in CF8.
- IsDefined(): CF6.1=136, CF7=611, CF8=1243. Double as fast as CF7, and nearly ten times the speed of CF6.
- CFC creation: CF6.1=9.7, CF7=3, CF8=69.4. Yep, performance here took a hit in CF7, but it's more than made up for in CF8.
Of course, in the real world you need to test whole applications, and not just specific language elements. So:
- BlogCFC: CF6.1=271, CF7=255, CF8=355. About a 30% performance gain.
- Adobe.com store: CF6.1=275, CF7=290, CF8=435. 30% performance gain there too.
In general we are expecting an average of 30%-40% performance gain across all application. And we have seen some apps where the gain is double and even triple performance.
Oh, and all of these tests were performed using CF6 and CF7 CFML, no new CF8 stuff. When those are added to the mix CF8 apps will run even quicker.
That is awesome! Thanks for sharing. I can't wait to see the speed improvements myself.
Thanks,

Did these number use JVM 1.4,1.5 or 1.6? Also, do you have numbers for cfdocument (pdf / flash) for various amount of memory (512,1g,2g,3g,4g). I think all of these numbers should be in a white paper
Any word on a release date, it is almost *MID* year ;)

Also is the team going to change the syntax from using "=" signs to ":" as noted in the comments from Ben's posts? I would welcome this change since I do a fair amount of jQuery Javascript programming and my biggest gripe against CF is the fact that Adobe doesn't follow standards when it comes to the language. If Javascript and all other languages use a ":", then why would Adobe take it apon itself to use a "="?
Dan, very soon. ;-)
Tony, bug fixes are still being applied. As for changes, I highly doubt it at this point, but you never know ...
More to follow.

Very simplistic testing, but results nonetheless:
<cfloop from="1" to="10000" index="i">
<cfset foo = createObject("component","foo")>
</cfloop>
CF7 14 secs
CF8 2.1 secs
---------------------------------------------------------------
<cfloop from="1" to="10000" index="i">
<cfparam name="myName" default="dave">
</cfloop>
CF7 31ms
CF8 16ms
---------------------------------------------------------------
<cfloop from="1" to="1000000" index="i">
<cfset foo = "poo">
</cfloop>
CF7 47ms
CF8 31ms
---------------------------------------------------------------
<cfloop from="1" to="100000" index="i">
<cfset foo = arrayNew(1)>
<cfset arrayAppend(foo, "This is an item")>
</cfloop>
CF7 350ms
CF8 1500ms
---------------------------------------------------------------
<cfloop from="1" to="100000" index="i">
<cfset foo = structNew()>
<cfset foo.poo = "1">
</cfloop>
CF7 500ms
CF8 1266ms
---------------------------------------------------------------
<cfscript>
for (i=1;i lte 100000;i=i+1)
{
foo = structNew();
foo.poo = "1";
}
</cfscript>
CF7 157ms
CF8 78ms
In some places, I found CF8 to be a lot slower. Any ideas?

I am *not* able to reproduce the results neil talks about. I am seeing better performance with both CF8+JDK1.4.2_09 (and CF8+1.6_01) as compared to CF702/CF7 in all the areas he is talking about.
I am not sure what might have differed in his testing and mine. Please ask him to check:
- If he has both CF8 and CF7 (or CF702) on the same machine.
- Settings like Whitespace management, trusted cache, Number of JVM threads are the same.
- Debugging is turned off on both

I've found that both CF6 & 7 have very poor performance on large lists (thousands of items). Performance seems to degrade exponentially with list size. My wild guess is it's related to the "Shlemiel the painter's algorithm" issues that Joel Spolsky describes so elequently here:
http://www.joelonsoftware.com/articles/fog00000003...
Is that close to the mark at all? It'd be interesting to see a performance comparison with CF8 on large lists.
Lists are slow because there is no list data type. A list is actually a string, any string. The list functions parse the string looking for delimiters, so as to allow you to extract values. If you want element 100 from the string it needs to be parsed (using , by default, but you could use any delimiter actually) and that member needs to be found. Every access is a string parsing exercise. And this has to be performed on every access, because the delimiter for one list operation may not be the same as the delimiter on the next. And so on. As a rule, lists are great because A) SQL uses them, B) HTML form fields come back as them. But for any longer list, or for any data accessed and manipulated frequently, use arrays or structures.

I'm using the query2csv script from CFLIB.org, and it literally takes about 2-5 minutes to download data from my current production environment on 7. Seems to take just seconds on 8!! Awesome!
Following are the issue description
Have an Oracle Database with Character set as AL32UTF8 and NLS_LENGTH_SEMANTICS= Char
I have created the table Table1 with the Columns as col1 char (1 char)
Inserted the values as "A"
When I use the query Select Col1 from table1 in Toad and SQL Plus it just returning data without the spaces
Returned
"A"
When I put the same query from CFM template it adding trailing space
Eg: ‘A ‘
I found an issue with Coldfusion 6.1 as well as Coldfusion 8 beta need to test the same in the Coldfusion 8 Final version
Enviornment : Coldfusion Mx 6.1 , 8 Beta
OS : windows 2000
Driver :
Coldfusion Oracle Native option
Coldfusion Oracle Thin driver option
ODBC Driver

Under this it creates a folder "bin/client/jvm.dll" file. I edited the C:\ColdFusion8\runtime\bin\jvm.config for java home to:
java.home=C:/Program Files/Java/jre1.6.0_02
And then CF 8 refused to start. After a bit of head scratching I realised CF 8 looks for a folder called "server/jvm.dll" so I simply copied the "client" folder to a new folder called "server" and hey presto - it worked.
I hope this helps others not have the same problem I did trying to work out why it wouldn't work and why they may be having problems with CF randomly crashing and re-starting under CF 8.

structNew()

I contacted Bluedragon directly for some advice on how to tune it. They replied (said to remove the JRun Connector Filter from the ISAPI Filters in IIS) and I did see some improvement, but I was still unable to get .NET to run faster than the JVM in CF8.
Our company is getting a lot of input from outside consultants that CF does not scale - so I am trying to fight back. Was very encouraged by my personal result - curious if there are any benchmarks that I could reference that are recent and industry accepted.

Is it possible to compare performance of cf8 server, .net server and a java server
