The mount list, `br0`, the GPU name and the 12 GiB VRAM size are constants in `Perf.qml`. +The CPU card ends with the five heaviest processes, by CPU or by RAM (a +toggle in the card, not saved). They come from one `top -b -d2` that runs only +while the page is open. A frame is published once top's output goes quiet, +and the first is skipped because top computes it over each process's whole +life, so rows appear about 2s after opening. CPU is per core, as top shows it, so a +busy process can exceed 100%. + The cache card runs `du -B1 -d1` once each time the page opens, 28ms over 2 GiB, instead of reading conky's 15-minute `cachesize.txt`. The largest child is yellow, red when it holds over half the total, as conky had it. |
