I did some testing and found that converting a big ass list (20k+)
used with numerous listgetat and listsetat, listdeleteat commands to an
array for use with the equivalent array commands, and then back to a list
for storage in the client scope was faster than working with the list in
CFMX.
It looks like you have to do StructNew within the loop for every iteration.
In your code you are only doing that once, for the first array element.

Darren,
Try looking at the problem differently. You can treat your query as
structure of arrays. If you do this you won't have to do any conversion
at all. Simply set up a for () or cfloop from to index loop and out
put only the values you want.
cfloop from=1 to=#news.recordcount# index=i
If it's a one-dimensional array, you could do this:
cfloop from="1" to="#ArrayLen( array_name )#" index="i"
#array_name[i]#br
/cfloop
For a two-dimensional array, you could do this:
cfloop from="1" to="#ArrayLen( array_name )#" index="aRow"
cfloop from="1" to="#ArrayLen( array_name[aRow]
How would i display the entire contents of an array?
Use CF_Show to output it on screen (Developers Exchange).
And looking at the source code might give you an idea of how to code what
you're after.
