We aren't seeing any performance problems on this per-se. But that just seems like a really odd graph to me. Can anyone explain it? In particular, how regular it is?
What's the scale on the bottom there? The label says "by week" but the way your message is written makes me think it's actually a much smaller time frame. If those valleys are around around five minutes apart, those are the checkpoints finishing; the shape of the graph is right for it to be those.
