我不认为你有什么特别的问题。我觉得你的系统慢是因为同时运行的东西太多，内存满了开始用页面文件。你已经确认关掉生成后 CPU 掉到 0%，所以 CPU 占用肯定全是空闲优先级的。0.3.1 里没有任何会影响这些的改动。
ORIGINAL · 英文原文
I don't think you have a particular problem, I think your system is laggy because you're running a lot of things at once and hitting the pagefile because memory is full. You confirmed when you shut off generation that your CPU drops to 0%, so the CPU usage is definitely all idle priority. There's nothing in the 0.3.1 that would affect these things.
