End-to-end benchmark results

This page is intended to collect the latest end-to-end benchmark results produced by Hydra's continuous integration (CI) system from the latest master code.

Please note that these results are approximate as they are currently produced from limited cloud VMs and not controlled hardware. Rather than focusing on the absolute results, the emphasis should be on relative results, such as how the timings for a scenario evolve as the code changes.

This looks fine; but need to understand and explain why the script sizes and such have changed.

Can you please investigate and let us know why? Thanks!

[locallycompact]

The script sizes have changed because this is rebased on top of the aiken upgrade. #1816
