Copying files using MTP leads to 99% disk utilization

Question

Since Android phones are no longer mounted as an external drive I'm having an issue with a copying of large amount of photos from the phone (no matter what - LG G3, Galaxy S7) to the laptop (Windows 10).

It starts at pretty good speed - I can see file name changing 3-4 times per second in the copying dialog - and then getting slower and slower till the moment when single file name could be displayed for up to 10 sec.

I would probably just live with it but I found that laptop's performance degrades as well during this process as copying brings 99% disk utilization while transfer speed is far below the maximum for the SSD:

How to track down and fix the reason it is happening?

Based on this answer:

This is a problem in communication's protocol:

The MTP and PTP standards do not support direct modification of objects. Modified objects must be copied out of the device and reuploaded in their entirety, which can take a long time for large objects

And Based on this article:

• https://vxlabs.com/2014/11/06/use-adb-to-bypass-dog-slow-mtp-transfer-of-files-from-android-to-linux/

It suggests to use ADB to transfer files, but in Linux not Windows 10.

To use ADB on Windows, follow this:
