I'm not saying you're wrong, but where is the data to backup this assertion ? IMHO, this commit message should be describing how performance was tested and what the results were. Regards, Daniel

I can submit a new series with the performance measurements now that you've informally OK'ed Emilio's new patch. Is there some public script to automate that or do I have to cook my own?

Emilio proposed this for user mode: https://github.com/cota/dbt-bench IIRC he also has a Linux image that boots and shutdowns immediately. Hope this helps, Laurent

BTW, I just realized that my original cover for v7 did include results: https://lists.gnu.org/archive/html/qemu-devel/2017-01/msg02741.html Do such numbers need to be in this commit or is the cover fine? Thanks, Lluis

Please do copy that info to the commit message - when someone looks back at git history in a year's time, they'll have the commit message right there, but will rarely think to look through the mailing list for a cover letter with data.
