Hi Julian,
we conducted extensive performance optimizations in order to reach an I/O performance that is roughly on par with native Linux. The article describes those steps in detail.
This is amazing! Can you estimate how many man-months you needed to get this done?
thanks. :-)
We have been working on the topic since May with varying members of our team. E.g. Stefan did most of the L4Linux and Fiasco.OC-specific work, Sebastian was focused on USB and networking, I was responsible for SD-card and HDMI whereas Martin supported the HDMI topic as well. That said, we have constantly discussed our steps within the team. It was great to explore the platform together. I cannot be specific about the number of man months because the work described in the article is just a sub set of the work we did during that time.
Cheers Norman
