Last week I spent half an hour comparing /coldfusion /vs /coldfusion
cfscript/ vs/java cfscript/ vs /javascript cfscript/ and I was kind of
surprised by the result, so I thought I would share it (+I saw on
another thread some questions about cfscript javascript speed):
* CFscript language=javascript is quite extremely buggy: issue #416
and #417
* CFscript is about the same speed as coldfusion
* *CFscript language=java is 100 (!!!) times as fast as coldfusion* in
calculating pi*.*
Especially the third point I would love to hear *why *the difference is
*that* big.
Results (for the code see below):
* JavaScript cfscript: uncheckable due to bugs, probably ~45000
milliseconds (based on only 10000 loops multiplied by 100)
* Coldfusion: 2000-2200 milliseconds
* Coldfusion cfscript: 2000-2200 milliseconds
* Java cfscript: 15-25 milliseconds
And the code:
/javascript/:
<cfscript language="javascript">
function x(){}
var Pi = 0;
var n=1;
for (i=0;i<=1000000;i++){
Pi=Pi+(4/n)-(4/(n+2))
n=n+4
}
$cf.print( Pi );
</cfscript>
/java/:
<cfscript language="java">
double Pi = 0;
double n=1;
for (int i=0;i<=1000000;i++){
Pi=Pi+(4/n)-(4/(n+2));
n=n+4;
}
cf.print( Pi );
</cfscript>
/coldfusion/:
<cfset Pi = 0>
<cfset n = 1>
<cfloop from="0" to="1000000" index="i">
<cfset Pi = Pi + (4/n)-(4/(n+2))>
<cfset n = n+4>
</cfloop>
<cfoutput>#Pi#</cfoutput>
/cfscript/:
<cfscript>
Pi = 0;
n = 1;
for (i=0;i<=1000000;i++){
Pi=Pi+(4/n)-(4/(n+2));
n=n+4;
}
</cfscript>
<cfoutput>#Pi#</cfoutput>
