Add time tracking like serializer

[TheoD02]

Hello

What do you think about adding a time information like proposed in Symfony's Serializer bundle ?

This would give us a quick indication of which mapping is slow and investigate

PR welcomed, should not be that hard

[joelwurtz]

Is it possible to have more information on what we want to expose/track?

What kind of information you want to add ?

How do we organize the UI related to the data we want to show in profiler ?

Not sure i would create an item for each transformations

I would create a specific tabs, that list mapping grouped by source / target with :

• min time
• max time
• average
• standard derivation
