[dpdk-ci] DTS Performance Improvements

[Owen Hilyard]

Hello Everyone,

I've added another section to the DTS Usability and Developer Feedback
Document
<https://docs.google.com/document/d/1c5S0_mZzFvzZfYkqyORLT2-qNvUb-fBdjA6DGusy4yM/edit#heading=h.bli76tj5btqm>
(Performance
Improvements) which contains my suspicions about the slow parts of DTS. I
would like to reiterate that this is just my experience from watching DTS
run many times, and is not backed up by data. The only piece of information
that I have that is not in there, because it is CI specific, is that having
multiple NICs in a server is essentially a multiplier on the amount of time
it takes to deliver complete feedback. When I tested nine months ago, I
found that it takes well over 24 hours to run all of DTS, so a system with
2 NICs would take more than 2 days, 3 NICs would take more than 3, etc.

Owen Hilyard.
