Subject: (code) Looping is faster in 4.5.2
In the past both myself and many others have written and said how CFLOOP is
faster and more efficient than the loops within CFSCRIPT. I was just doing
some tests and found that this is no longer true. It seems that as of CF
4.5.2, CFSCRIPT loops are the more efficient loops with the for loop looking
slightly better than the while loop. These are my findings, but I'd like
others to play with this as well and give me their results. Below is my test
code. Each section is as exact in comparison to the others as I can make it.
<CFSET start=GetTickCount()>
<CFSCRIPT>
i=1;
While (i LTE 1000){
test=i;
test2=test+i;
i=i+1;
}
WriteOutput(test);
</CFSCRIPT>
<BR>
While: <CFSET WriteoutPut(gettickcount()-start)>
<BR>
<CFSET start=GetTickCount()>
<CFSCRIPT>
for(i=1; i LTE 1000; i = i + 1){
test=i;
test2=test+i;
}
WriteOutput(test);
</CFSCRIPT>
<BR>
For: <CFSET WriteoutPut(gettickcount()-start)>
<BR>
<CFSET start=GetTickCount()>
<CFLOOP from="1" to="1000" index="i">
<CFSET test=i>
<CFSET test2=test+i>
</CFLOOP>
<CFSET WriteOutput(test)>
<BR>
CFLoop: <CFSET WriteoutPut(gettickcount()-start)>
