Looping over lists, and list functions are always slower than referring
directly to an array or a query
There is another alternative;
If you're not doing a CFOutput
<cfscript>
for (i=1; i lte big_query.recordCount; i=i+1)
{ do stuff with big_query.Column1[i];
}
</cfscript>
or if you need CFOutput
<cfloop index="i" from=1 to="#big_query.recordCount#">
do stuff with big_query.Column1[i]
</cfloop>
