5.6.x Editor Performance Issue

Hey,

So, I use a mac sierra and ever since I updated my project to Unity 5.6 (and 5.6.1), my Editor is EXTREMELY slow… honestly it is making me mad. The issue is that whenever I compile code, the first time I do anything, it takes 5-10 seconds loading something… for example, I open unity… then I click on “file”, since its the first time, it takes 5-10 seconds to open the file menu… then I right click a game object on the hierarchy, it takes another 5-10 seconds to show the dropdown… then I want to add a script… it takes 5-10 seconds to add said script… everything I do takes 5-10 seconds loading something the first time I do it… and the issue is, if I compile code OR hit play on the editor, when I get back to editting, I have ALL those delays again… its basically impossible to work like this, and it clearly started with 5.6, as even 5.5 was running nicely over here, was actually very fast.

Anyone having this issue?
Thanks for the attention,
Best regards,
Allan

I don’t have it that bad - for me it doesn’t happen every time I compile or hit play. When I first load up our project in Unity, for the first 10 minutes or so it is super extremely chuggy, like you say; every action takes a few seconds, including clicking on an object in the hierarchy, moving/rotating the scene camera, or even typing in the search bar. I ran the profiler on the Editor during that once, it was doing some sort of GI calculation (we don’t have GI baking or precalculating on so it shouldn’t have been baking GI, nor did it show the percentage in the corner).

And my computer is a pretty top-of-the line PC with 64GB RAM, i7 6900k, SSD drive.

I see, yeah that is exactly the kind of behavior I am looking at, but permanently (not only first 10 minutes). We also dont use any kind of GI baking or anything, and as you said… its strange that this would be happening when we click on the search field to type something… actually even simple actions like, once I select a game object, if instead of CLICKING on another object I use the arrow keys to move up and down… I get a 5-10 seconds delay the first time lol… as if it had to load the lib that says “oh, so arrow keys change the selection too”

Same as with you, my machine is pretty good as well… not as good as yours but pretty close.
