Description Igor Stoppa 2016-03-23 11:33:02 UTC 
In some cases, it can take quite a while for rebuilding a package.
To the normal user, this might look like the machine is stuck.
But even running ps/top in a separate window doesn't give any idea about how long it will take.

It would be useful to have statistics (for example embedded in the SSTATE content) that would support the execution of:

bitbake -c show-stats recipe

Then one would know how long it took to perform a task, on the machine that populated the SSTATE, and weigh the decision of rebuilding some or all of it.

This probably ties in with the work I have done for bug 5383 (which went significantly further than the original request; I've attempted to produce a general solution that would work for any task).
Comment 2 Igor Stoppa 2016-03-31 10:45:42 UTC 
Yes, it looks like it could go under that umbrella.
If you prefer to consolidate them, feel free to add this proposal to 5383 and mark this as duplicate.
Comment 3 Richard Purdie 2016-03-31 14:03:52 UTC 
Marking as duplicate as agreed.
