compiing c# scripts (busy for 45 seconds) freeze

Does it eventually finish, or was 45 seconds too long to wait? How long it takes depends on how much compiling it has to do, and the performance of your computer hardware.

 

Does the process take that long usually? It's freeze, means apparently no progress, 45 seconds or whatever is not matter, tho I waited 20 or 30 minutes. My machine is not a bad one. gtx 1050 ti, intel core i7 gen 7, 64 gb memory, ssd.

 

See the task manager
The older version (unity 2019) just freeze until compile to be completed
The unity 2020.2 just shows you a progress bar on the freeze time

 

For me, Unity usually takes about 30 seconds every time I make a change in C# and it's a small game (and I also have a machine with good specs), so yeah. However, 20 to 30 minutes is definitely not normal. I wonder if there's something on your system that could be interfering with Unity's process? Maybe an antimalware program?

 

Your CPU is very limited by today's standards. Unity's complation stages are becoming progressively more multi-threaded making it very important to have a high-core count processor. Intel's 7th generation processors are just four cores when most modern processors at that tier are now 8 (Intel) to 12 (AMD) cores.

Check out assembly definitions. They exist to minimize the amount of code that is recompiled with a code change.

The same CPU compiles the same script better in previous unity versions
The problem is from unity side (if it's a problem )
I will compile with Q8400 in a few seconds on 2020.2

 

I don't see them saying that anywhere in this thread.

 

i'm developing on a i7-8550u (Dell XPS) most of the time and compile times are pretty ok, normally between 5s to 20s for changes. It seems you are on the package manager screen, did you just import some package with tons of scripts?
