LabVIEW Environment, Editor and Configuration Windows are very slow.

I've tried other things, but still no better. I've attached a video that shows what I was talking about.

I get decent speeds with an empty front panel. I add a few controls and then it just dies.

My block diagram speed is decent over all.

You only have 2 hyperthreaded CPU cores, so 50% is one core fully saturated. Does the task manager say that all this is really used by LabVIEW? (Sort the task manager by CPU% column).

(True story (I doubt that is your problem, though): I recently troubleshooted a computer that was claimed to be suddenly very sluggish overall, and it was almost impossible to click or move things. Turned out the wireless mouse button was faulty (batteries OK!) and a large percentage of clicks never made it to the OS.   Everything went back to normal after replacing the mouse!.. )

You're right, I forgot to clarify that. The process is slightly lower, just at 30% to 38% on average. Even with lag worse than in the video the process usage does not climb.

What app shows the second largest CPU usage during these times?

There's no app consuming a large amount of CPU, just LabVIEW.

List processes by Disk Usage. 

100% Disk Usage will also slow down a PC.

Lower spec machines running Windows 10 seem to have a lot of trouble with Virus and other "Security" software. 

I recently setup an i5 Dell where the combination of McAfee and MS anti virus software rendered the PC basically unusable before any other software was installed on it.

This is also not the case. Disk usage remains at 1%, even during worst freezes. For the record, the software executes perfectly well if I've compiled it and or built it.

Have you tried lowering "Limit Compiler Optimization" under the Tools/Options menu, Environment tab, at the bottom.

Set that slider to 0, then you need to make Labview recompile its VIs. I think you have to close Labview then reopen to make it recompile with the new setting. To be sure, make a cosmetic change once LV is reopen and save the VI.

They recommend to setting the value back to 5 when done.

Another TRUE story. Talking about odd behaviors reminded me of a work laptop I once had (I think it was a Dell? Maybe HP?) . Everything was running like a 286 with 500MB RAM.... super sloooow. I had the IT department disable virus scanner since it was regularly consuming 20% CPU, but no joy. This went on for a month with very little support. After much research on my part, I discovered it was due to a crappy battery. Remove the battery (running on AC) and the laptop went back to normal
