cluster struct with refnum slows down V:I execution

[alpony01]

hello..to  to pass variables among various V.Is in a single struct i have had to adopt  to a system where by i have a cluster composed of an integer element and a refnum that points to an array of clusters...however ,the execution of various operations seems to have slowed down greatly. the .PNG image i have attached shows an example of how am currently accessing these variables..I would like to ask if there is any improvements i can make to help speed up the duration of execution   ..thank you

Yes it'll be slow, as control refnums will work on the front panel control in the UI thread. Why dont you wire the cluster array and index it directly instead?

Yeah, using property nodes to get/set values is terribly slow.  And I am talking 1000s times slower.  That is why that is one of my pet peeves with some people's code.

I agree that you should just have the actual array in your cluster.  It'll make like so much easier on you.  Either that or use a Data Value Reference.

thank you both for ideas,,they should solve my prob..i was hoping i could just optimise the current structure but i guess i have to change it

If you typedef'd the cluster, it might not be too big of a deal.  The only thing that would happen - other than making the front panel all out of whack for each VI using it - would be that you'd have to deal with the data directly instead of getting it from a value property node.
