Move Stacked Sequences from the Palette

[Spectre_Dave]

There has been a lot of discussion on this but no LabVIEW Idea (that I was able to find). Please move the Stacked Sequences from the Programming Palette to a "retro" or "classic" palette. This is dissuade novices from overusing them

Retain them for legacy code but please remove them from the Programming Palette

Lets vote this in and get rid of Stacked Sequences forever.

I would go so far as to release a patch to remove them from all Installed LabVIEW Versions!

Just because the subject comes up now and then to not just Move but REMOVE the SSS I took the time to put a test bench together (Source LabVIEW 2013 (13.0f2 x32) on a dual core Win 7 x64 OS.

For those that want to play, thats a snipette created with the CCT.  The Boolean "Fail" indicates the test cases do not yield equivalent data.  If you light that baby up you did something wrong!

As suspected, none of the test cases have performance that matches the SSS with Sequence Locals.  A Small surprise: The 1 additional unneeded tunnel the direct SSS-FSS replacement adds (presumably, to maintain the paradigm against possibly executing code parallel to a single frame of a SSS) does have a measurable performance impact of @%2 on my system.  I had expected any performance impact would be in the dirt.

So,  Kudos to move the SSS to prevent abuse.  But, lets stop beating up on this hard working node that gets the job done like nothing else!

Whatever you have attached above does not appear to be a snippet. Maybe you should start a new thread in the LabVIEW forum for discussing performance issues and attach it there once more.

If there are performance differences, it just means that the compiler needs to get smarter. 😄

For once I'm a bit ahead of you Christian

Check the u-nuggets thread

Do we really need to engage R&D's time to write an optomization for spaghetti code?
