Using Windows Performance Analyzer to identify slow windows 10 shutdown

My windows 10 laptop is taking around 1 - 2 minutes to shutdown or sleep. I have followed the steps given on this question:

How can I identify the culprit of my slow Windows shutdown?

I used the Windows Performance Analyzer and generated an output shutdown_BASE+DIAG+LATENCY_1.etl

The graph looks like this:

I am not an expert of this kind of graph and there are so many graphs to look at, but from what I understand the graph shows that it takes around 11 seconds to shutdown, while in reality, it takes more than one minute for shutdown or sleep.

Can somebody guide me on reading the graph to identify the main problem of my slow shutdown?

System information

Windows 10 Pro, i7-2630QM, 12GB RAM, more than 500 GB free space.
Programs used: VirtualBox, Cisco VPN Client, Avast Free.

EDIT

This is the content of my FullBoot.Shutdown.wpaprofile

The services.exetakes around five secs, but it is still far lower than one minute.

In WPA.exe, clock on Profiles->Apply->"Browse Catalog" and select FullBoot.Shutdown.wpaprofile.

Now you see this overview how long shutdown takes:

In this sample it takes 8s to shutdown. 2s are needed to close the user session (were 1.2s were spend to kill onedrive.exe) and shutting down the windows kernel/services takes 5s.

Look at your data to see where Windows spends most of the time.
