Please define 'Web performance'.
I've just seen a demo of Dynatrace which is

Basically this is a query of the form 'Please suggest open source
alternatives to proprietary package X', which generically (1)

Perhaps you should back up and describe what specific real-world problem
you're trying to solve. I doubt that your specific pragmatic problem
centres around any Dynatrace, LLC product.
OTOH, it's possible you have no actual pragmatic need, and are just
curious if the small number of people familiar with proprietary package
X can suggest an open source alternative with the same feature
