- Not stopping AWS Glue with an insane amount of DPUs attached when not using it. Quote "I don't know I just attached as many as possible so it would go faster when I needed".
- Bad queueing of jobs that got deployed to production before the end of month reports came out. Ticket quote "sometimes jobs freeze and stall, can kick up 2 retry instances then fails", not a big problem in the middle of the month when there was only a job once a week. End of the month comes along and 100+ users auto upload data to be processed, spinning up 100+ c5.12xlarge instances which should finish in ~2 mins but hang overnight and spin up 2 retry instances each
- Bad queueing of data transfer (I am sensing a queueing problem) that led to high db usage so autoscaling r5.24xlarge (one big db for everything) to the limit of 40 instances
A) stay on and help integrate an external team for up to 16 weeks (reduced hours, freedom to interview and apply elsewhere) B) stay on and wrap up the current sprint and tidy up some documentation for up to 8 weeks C) finish out the week and receive 6 weeks separation pay. All options also allowed me to keep insurance until I found a new position as well as keep my company provided tech. It really made me appreciate the people at the company overall, minus the person who was making the changes (which has since been canned and some of the engineering efforts at the company have stalled which is sad)
So for example the CPU is rated at 1.1ghz base and up to 3.5ghz boost. In the thermal throttling video we see it hold steady at ~10w and ~1.5ghz sustained. As far as Intel/Apple is concerned this isn’t thermal throttling because it is still higher than the base clock. Previously they would list all core boost clock and I think if it fell below that it would technically be thermal throttling
From this video: https://youtu.be/hB1aP2OnUJA we can see it quickly gets to 100c and stays there despite ramping the fan up. So while a quad core that can turbo up to 3.5/3.8ghz sounds awesome, for heavy sustained performance it looks like it’s definitely going to be clocking down to 1.5ghz or so.
This isn’t a surprise to me but I think some people just see 3.5/3.8 quad core and think this is going to be right on the heels of the MBP 13
