Hi Elliot, Actually, after more investigation, the slowness of nine.bb.net I got was just due to latencies between EU(where I am) and US (where buildbot.net infra is)
I looked at your trace, I can only see one place with 100%cpu for a while, and that is while fetching the list of builders. How many builders do you have?
