Hopefully not a silly question...

How can I accurately measure the time it takes to open an email in Outlook (Classic)? i.e. from me double clicking the email in the Inbox to the email Window finally opening?

Is there like an event timer utility that can hook into certain OS/App events (e.g. double click and window open) that can measure the time (e.g. in milliseconds) in between or something?

I appreciate it's somewhere between 1-2 seconds on my lowly i7-6700K Windows 10 PC, but I want to get a more accurate number.

The idea being I then want to time it on a faster machine - e.g. an i3-14100 or even an i5-14400 for comparison purposes.
