Do + you think there is hope to \"spread out\" GC latency to keep it + below say 15ms, even if more frequent (without just repeating many + short GC\'s in a row)? + - A: The only reasonable \"spread out\" is deferring GC to + \_after\_ that scrolling.

Since GC cons threshold is raised to + \~1G (gcmh-high-cons-threshold) while Emacs is used - you will + face a really bad hang (seconds to tens of seconds regularly). + Ends up not helping much, recommend increasing + gc-cons-percentage=0.2 or so instead. +- Q: + - A: +- Q: Is there some way to free up memory (such as via + \`unload-feature\`) in Emacs?

Essentially the question is at what point all my daily mostly-textual Emacs usage doesn't come close to using all the available memory on a 32G sys? (but my mind went more to being concerned about new cons/alloca and fragmentation for the intra-day use) I'll have to look into it more before being cogent. One more onto the todo list then :) + - A: for increasing thresholds up to RAM limits, do remember that individual GC time will increase - with 32Gb RAM you will likely make individual GC prohibitedly slow sooner than later. I'd say that it only makes sense to increase the thresholds when you have multiple agglomerated GCs. Going beyond this is of little use.
