Re: [cbi-dev] much much slower build times since last Friday


I have two other symptoms that may be related:

1- I am getting random stalls when connecting to the CI instance from my browser. When I access a page one or more elements is very very slow to load. Normally a ci page opens near instantly, but when I look at the Network tab in Chrome, random elements stall for 20 seconds (and always almost exactly 20 seconds). See my waterfall screenshot below for how took 20.21 s.

2- I had a problem since the upgrade with git commands failing (see Bug 570783) - I worked around this as recommended with

Hi folks,

I don't know if this is a consequence of the cluster upgrade on Friday, but since Friday night I have seen a consistent massive increase in build times on all my CDT builds. 

- Quick(ish) Builds which used to take 10 minutes are now taking 30-50 minutes[1]
- Main build which used to take just over an hour is taking 2+ hours[2]

The slowdowns appear to be across the board, and I can't see anything in the logs to indicate the cause of the slowdown, every part of the build just seems to be much slower.

One possible thought I had was that perhaps the cluster upgrade is enforcing cpu limits in a stricter way??? 

Thanks for any insights.
