Reasons for Variations in OS File Checksum Verification Times

We have tested the sample flashing application with the ‘etcher-image-write’ package. After flashing, the OS file checksum verification takes different amounts of time in different environments.

For example:

  • Windows and Mac take 3-4 minutes for a 2GB .img file.
  • Linux takes 30-40 seconds for the same file.

What could be the reason for this?
