Problem with slow execution on a cFP-2120

Question

I have an application that runs on a cFP-2120, using web interface for the user to interact with the program.
I have noticed that in order to get the web interface to get updated I have to use property nodes and write to the value property, see this article:

However, this seems to give me a serious performance hit, as described here:

I have tested with this code, and with my LV 8.2 a loop that uses 277ms to complete when writing directly to a indicator will use 203159ms when using a property node.
So, I need to update several front panel objects using the value property, but can't afford the cpu time. Does anyone have a suggestion how to do this as efficiently as possible? The problem is apparantly that using the value property requires the front panel to be loaded - can I for instance avoid doing this once for each variable?

Answer 1

I've changed the vi now so it only writes to value property when a value has changed. This has cut execution time in half, from 500ms to 250ms. I still think this is quite a lot...
To give you an indication of "size", the executeable is 1210kb with 2 dll's of 872 and 168kb.
I've not tried deploying a smaller (cut down?) version - what exactly do you mean?
With regards to writing to value instead of locals or directly - I've had problems with the values not updating - but not always - and the first link does suggest a bugfix. I'd like to know why wiring to value property is sometimes needed and sometimes not.
