Description
At some point, we should add support for comparing traces:
* taking on the same machine at two different times
* taken on two different machines potentially at the same or different times
The UX for what the diffing should look like is very much TBD. We definitely need to take inspiration from other tools which do this (though not many try and allow for diffing full traces, they usually extract some aggregate and diff that).
One feature we definitely want of course is flamegraph diffing based on selections from each trace. We might even make this a top-level hero feature given its importance
