    380.000 concurrent sandboxes on 160 Epyc based server nodes. Crazy stuff

      that's only 12 sandboxes per core

        Um, how is that not impressive

          if it's agentic stuff, they likely aren't hammering a core constantly and they will maybe sit idle quite often between model requests, so it makes sense. I do wonder how much memory they allocate to each one though.

          it's just very efficient use of shared cores that is required to make these kinds of workloads cost efficient

            If they sit mostly idle, you can swap out a lot of the memory to SSD, I guess.

          A place I worked back around 2020 was running a Grafana instance per customer that got embedded on the web dashboard. We had 110 pods per GKE (kubernetes on gcp) 4 CPU node because that was a network imposed pod limit at the time. The nodes were usually idle--could have shoved a lot more on if not for the IP limit.

          I think around that time Grafana changed their license tho so you couldn't host OSS Grafana as part of your service.
