Introducing MicroProfiler memory profiling, flame graphs, diffs, and much more

Updates Announcements

I’m glad you like it!

We planned to release the diffs closer to the end of the year, but since we managed to finish this feature earlier, why not release it right away, right?

As for zooming in, it seems that zooming and the find feature are the most welcome additions overall, haha.

That makes sense! I was starting to realize that it might only apply for captures and not the regular view.

That said, I’d love to see X-Ray view for the regular, moving view of the MicroProfiler. This will make it easier for younger/less experienced developers, as recording captures can be quite a skill curve.

Including argument data is memory-intensive. This means we’d be able to display far fewer frames. However, your suggestion has got me thinking - maybe we can add detailed info only to those scopes that take an unusually long time. It’s worth researching.

Adding onto this; I saw no documentation on certain scopes, even after extensive searches on different engines. It’s not immediately obvious what a scope does sometimes, and I need to know when to blame you, not myself :grin:
For example, WaitForLock - who knows what it does other than the most highly esteemed engineers; but it chews up 30ms intermittently and that translates to stutters and I don’t like it and I’d love for it to be documented so I can plan ahead for a countermeasure.

Please please, pretty please? :pleading_face:

Would be super appreciated! Since we’re spitballing ideas: it would be super awesome if the client could attach some small basic data, to describe what the user was doing at the time. Our game for instance has a lot of different gamemodes and worlds, and so being able to prepend this information into the microprofiler dumps we receive from users would be amazing!

This is my current foremost issue with the microprofiler - scopes are not really documented anywhere. You may get lucky if it has a useful name, but otherwise it’s difficult to pin down. Hope comprehensive documentation can get released at some point.

There is information about some scope names in the documentation: MicroProfiler Tag Reference

This is very nice, thanks for the link! Don’t know how I missed it. I imagine some stuff is still missing, but this is quite a bit of tags.
