v11.3.0 slow and sluggish

[mspenard603]

Hi Gents,

 My MCUxpresso IDE seems awfully slow and sluggish. For instance, if I start typing there is pause the cursor. My workstation is a well spec'd machine.

What preferences should I be looking?

Hi mspenard603 

From my experience of using MCUXpresso IDE, it is not that slow. 

I suggest you create a new project under a new workspace to see it the problem is still the same.

I know some customer has similar problem as yours. they resolve the problem by disable firewall and virus defender. Please check this point as well.

Have a nice day,

Hi Jun,

 From my experience MCUexpresso IDE, is slow.

Anti-virus and firewall are disabled.

Other projects seem quicker. However, my project is quite large.

I also have an issue when I make a change under Properties. I have to let it sit a few seconds after hitting apply. Otherwise I get the following error:

SO your problem is related with your large project only.

One possibility is that the IDE heap size is not big enough, please follow this article to increase heap size.

If you ever rename the project, see solution in this thread,

Heap seems fine. I never run up against the current maximum. And it expands, contracts and does garbage collection. The lagging pauses seem to happen during garbage collection as well. Really annoying.
