Description
We often struggle to determine why a query was slow, in particular if it was caused by other tasks on the same machine using resources. To help with this we should include timelines for system resource utilization to the profiles. These should eventually include CPU and disk and network I/O. If it is too expensive to include these in all queries we should add a flag to add these to a percentage of queries, and a query option to force-enable them.
