Desired functionality

Not empty speed-measure-plugin.json

additional

chrome-profiler-events.json way to big to open in chrome. (Chrome crashes)

I can confirm that the speed measure file is empty on a fresh project in 7.0.3 too.

Yeah the speed-measure-plugin seems broken... I'm not sure why, probably incompatible with the webpack version we're using atm.

Big chrome-profiler-events.json are hard to open in chrome sometimes. I don't have a good answer to that. In the past when I had trouble with those I had to manually profile only on rebuilds or something. Using https://github.com/GoogleChromeLabs/ndb might also help but not sure.

[Lakston]

I took a look at the files quickly and the implementation looks ok so yes it might be a problem with the webpack version, I'll try to test that this week-end if I can find some time to do it!

Hi, any progress on that issue? It still happens in 7.1.0. Thanks.

[guillaumebouhier]

Issue is still reproducible on my side. Is there any workaround ?
