Checkout suddenly much slower on windows environment

[yeu-degroot]

Description

Since a few days, the duration of the actions/checkout@v3 steps on windows-2019 have dramatically increased.
This behavior is seen on all my repos (all private). Below a table showing an example of before/after.

Checkout step	Feb 17th	Feb 21st
1	13s	1m35s
2	8s	47s

The result is a huge increase in build (and billable) time.

The github status page does show some issues around this time frame, but these were all solved:

Platforms affected

• Azure DevOps
• GitHub Actions - Standard Runners
• GitHub Actions - Larger Runners

Runner images affected

• Ubuntu 18.04
• Ubuntu 20.04
• Ubuntu 22.04
• macOS 11
• macOS 12
• Windows Server 2019
• Windows Server 2022

Image version and build link

Current runner version: '2.301.1'
Operating System
  Microsoft Windows Server 2019
  10.0.17763

Private repo

Is it regression?

Yes, sorry private repos

Expected behavior

The build times should be fairly constant.

Actual behavior

Build times explode. Burning down our build minutes too fast.

Repro steps

Compare build times on any windows environment from before Feb 18th with today.

Hello! Please report to the https://github.com/actions/checkout repo as they maintain the setup task primarily and can tell what happens on windows better.
