I posted the same question in NI forum, but, the problem is serous for me, so I try also in this community.
I upgraded a large SW developed in LV 7.1 to LV 8.2. After some error corrections I saw that a large Vi in LV 7.1 (a Vi template, .vit) that was 18 MB, in LV8.2 was 2.6 MB !
The editing of this Vi is very very very slow, and it's unacceptable. When I save it I can have a coffee break !!
Also, to open the reference to this Vi it's necessary 35-40s but in LV 7.1 2 seconds were enough.
In the Vi there isn't BMP, large strings.., it's saved in 8.2 format (I coverted and then I saved it), there is a digital waveform graph initially empty and there is 2 slide bars that overlap the graph (I update their position when windows resize).
I discovered where LV "wait " a lot of time. The Vi is a "clone Vi ", so I open it in the way that you can view in the attached vi. In the Open Vi Refernce block (there is a break point) the CPU work at 100% for a lot of time and , I think, this is the only reason of slowness . After this block, the execution is ok and it's output is:
VI name: READ_DIGITAL 12.vi
VI path:
Application instance: Main Application Instance
Refnum (in hex): 0xCEB00025
When I open the vi to edit it, itsn't slow..but it's very slow the editing...
Labview 8.2 very very very slow

Any suggestion to solve this big problem ?
