Fast refresh is very slow

Bug report

Describe the bug

Fast refresh takes at least 20s on my build on 9.4.1. Reverted to next 9.3 and the hot reload is nice and fast.

To Reproduce

Just create an application with the Default Starter Template, should happen there as well (shorter compile times, 7-10s but still seems like a lot).

Expected behavior

Would expect fast refresh to be .. fast :D

System information

• OS: Windows 10 (WSL Ubuntu)
• Browser: Any
• Version of Next.js: 9.4.1 , 9.4.1-canary.5, next@canary
• Version of Node.js: 13.8.0, 14.3.0

Please provide a full reproduction then we can investigate. Also try next@canary

This happens on the Default Starter App template as well (it's slightly shorter there 7-10 seconds).

Seems to be what's happening here #12797 , as the Antimalware Service Executable flares up on every compile, but next@9.4.1-canary.5 does not seem to solve this particular issue for me, still seeing long compile times.

I've upgraded node to 14.3 as well, no dice.

Please be sure you're upgraded to 9.4.2.

Tried 9.4.2 as well, same issue.
Going to use 9.3 for the time being, thanks for the help.
