How to measure time it takes to open an email in Outlook (Classic)

[Cb27]

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.

I don't think there will be any way to time the opening of emails. It will be dependant on other programs running, not the email program alone. Additionally, your ISP speed and other devices running on your network will also affect speed. Have you tried reducing the size of your OST and PST files? https://support.microsoft.com/en-gb...-and-ost-e4c6a4f1-d39c-47dc-a4fa-abe96dc8c7ef

I get that. The emails have already been downloaded and are sitting in the local .ost file, so broadband speed is not a factor here. I'm only trying to get an idea of how long it takes the machine to carry out the instructions to open the email.

I know it will be faster on a machine with a faster CPU, I just want to be able to quantify it.
