The key here seems to relate to the "Total" line triggering a new line part way through the package download. The faster the host, the less noticeable the jitter. This is from the newer box that I though was NOT affected: linux-docs-5.12.9.arch1-1-x86_64 Total (0/4) 0.0 B 0.00 B/s 00:00 [--------------------------------------] 0% linux-lts-5.10.42-1-x86_64x86_64 22.0 MiB 5.75 MiB/s 00:04 [######################################] 100% Total (1/4) 20.9 MiB 6.08 MiB/s 00:17 [######--------------------------------] 16% linux-lts-headers-5.10.42-1-x86_64 74.3 MiB 5.85 MiB/s 00:13 [######################################] 100% Total (2/4) 95.5 MiB 6.08 MiB/s 00:05 [############################----------] 74% nodejs-16.3.0-1-x86_64.42-1-x86_64 22.7 MiB 5.57 MiB/s 00:04 [######################################] 100% Total (3/4) 117.8 MiB 6.06 MiB/s 00:01 [##################################----] 92% Total (4/4) 127.8 MiB 5.73 MiB/s 00:22 [######################################] 100% It was affected, it just wasn't as noticeable when pacman was running because the screen refresh was fast. Also note, I do all updates over SSH (and Wifi) to headless boxes, so there many be some network delay contributing as well. But the point being, for 12 years I have never seen anything like this issue, and now, it is quite notable. -- David C. Rankin, J.D.,P.E.
