I have an labview application which takes around 50% of CPU usge but wen the same is running throgh code it takes only maximum of 12-16% can any body suggest me what might be the wrong.

Not looking at the code but reading the reactions...

Could this be solved with a strategic wait in a loop somewhere?

When moving between development and the exe we have more threads available to hammer the CPU and the default number of threads for LV is well below 100.

There are a zillion parallel loops and they are all throttled by SQL queries.

OK.

Wrapping the SQL queries in a sub-VI may also help but I will have to tune this week-end to find out what happened to Batman.

C'mon guys. This whole thing could be solved if NI would just implement zoom!

Dear all.... anyways... what the code i made is according to my application requirement.... without altering the code i got the cpu usage of my appliction lowered...  just i split my application into two... it serves my purpose..

Thanks for the Soupport

I'm not even sure how to respond to a comment like this.

All I can think of: So your application requirement is to write convoluted code that requires a screen the size of Texas to see it?

I can also see that the basic response was "I'm going to ignore all of the valid and valuable criticisms and suggestions that were made and just do it my way".

OK. Good luck.

We are all smart alecs, but no one rewrites her/his code.

I just found out about this thread today. I want to figure out how smurthy got into this situation.

smurthy (if you're still reading this thread):  Did you start this application with a blank VI?  And what kind of LabVIEW training have you had up to this point?  Is this your first reasonably-sized LabVIEW application?

Ultimately, we want to see this kind of application solved with a cleaner architecture.  I'm looking into ways of making it easier to start off with a good framework for an application (as opposed to starting off with a blank VI).  If you're willing to provide me with these details, it will help me make future changes in LabVIEW that will help users like yourself design more modular, maintainable applications.

Hi ..

 I got the solution in order to reduce the memory usage of my application.. i tried out manyways to do it.. finally i increased delay in the 100 while loops and my cpu usage is now maximum 12% for whole application... at any cost i cant reduce my code as i need to pop up 100 vi's wen alarms occured....

Hi smurthy,

are you sure you need 100 different VIs popping up?

Maybe you can use one reentrant VI for that purpose?! (I'm pretty much sure!)
