Print out clearly the runtime overhead for an isolated step #124

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Right now when using the --profile flag details are printed out about the time 
taken to download missing files, creating the tree of hardlinks and then 
deleting it after the run. This data is not surfaced properly.

This FR is about surfacing this data at the Swarming level to be able to 
calculate the efficiency of the task distribution by calculating the overhead 
in seconds per execution time in seconds.

This requires both the new bot API to be able to surface this data properly.
