Very low cpu usage while compiling

[Druide]

Hello,

When I compile code changes in Unreal (version 5.3.2-29314046), I notice that the CPU usage of UnrealEditor in the task manager remains very low, around 1%. It takes me about 4 minutes to compile code changes such as adding a single UE_LOG in a default/empty project. My processor is AMD Ryzen 7 3700X 8-Core Processor.

Is there anything that can be done to better utilize my CPU (and hopefully speed up compilation time)? I tried the following suggestion but it did not seem to improve things https://www.reddit.com/r/unrealengine/comments/sqzbk6/speed_up_ue5_compiling_like_20_times_faster_my/

To compile, I click on this button, and I disabled live coding

Thank you!

I also have this issue at UE5.4.3
I have ssd nvme and 32 RAM. There must be some bottleneck in UE5.4.3 it self.
Googling for whole day but none can solve this compile low cpu usage
