How are you measuring pageload speed with GTM and reading it in GA4?

The guides I've found online send a page speed event for every view to GA4 with a parameter capturing the time. However, that quickly leads to high cardinality because explorations max out at 500 rows and a pagespeed event is registered for every pageview.

If I have more than 500 views per page, I'm unable to see all the values and do analysis on it (averages, distribution, etc.).

How are you using UTM ID? Are you actually generating a unique number code for each campaign? How do you go about generating the number if you are?

I work for a large company with lots of campaigns. Any advice on how to implement an ID system would be appreciated.

Also, any real life examples where UTM ID came in handy?
