I did a huge grafana upgrade from something like v7.x to v12..3.0 and now the load average is often between 15 and 30!
It's not obvious to me why though.
The VM it's on has 2 CPUs and 8G RAM of which about 4G is free. The average CPU use is just 18%. This would make me suspect iowait but it rarely budges from 0%.
Now, periodically the two CPUs are totally pegged though this only lasts a short time and the service still seems responsive. Maybe it's that?

Incomplete Air Mixing Reduces the Efficiency of Commercial Buildings Behaving as Virtual Batteries
Commercial building Heating, Ventilation, and Air Conditioning (HVAC) systems can provide flexibility to the electricity grid. Some researchers have found it convenient to model HVAC systems as virtual batteries. These models also better align with models used by grid planners and operators. However, experiments have shown that HVAC load shifting can be inefficient, and virtual battery models do not capture this inefficiency well. While the models typically use the average room temperature as t…

MeanSE: Efficient Generative Speech Enhancement with Mean Flows
Speech enhancement (SE) improves degraded speech's quality, with generative models like flow matching gaining attention for their outstanding perceptual quality. However, the flow-based model requires multiple numbers of function evaluations (NFEs) to achieve stable and satisfactory performance, leading to high computational load and poor 1-NFE performance. In this paper, we propose MeanSE, an efficient generative speech enhancement model using mean flows, which models the average velocity fiel…
