Out of curiosity just how many "headers" are we talking? As I mentioned, pan should handle north of 2 million now, given say 16-gig plus of RAM, but I really don't know /how/ /far/ north of that ~28 gig (RAM+swap) app- usable will get, now, nor do I know what sort of numbers such groups actually have now, so getting some sort of idea to calibrate myself against modern 64-bit pan and modern high-traffic binary groups would be useful. And also... I'm assuming that swap is at least SATA-3 SSD if not M2 or even compressed-RAM (zswap or swap on zram), and not legacy "spinning rust", which I can only shudder at the thought of, 8-gig into swap! Meanwhile, if people are going into swap enough to be a worthwhile discussion, we could do a subthread on swap and filesystem cache tuning (basically the stuff under /proc/sys/vm, often configured via /etc/sysctrl or the like). My system's old enough to be stuck on SATA-3 SSDs still, but swap and cache tuning have made quite a difference for me. (FWIW, 16 gig RAM here, gentoo system, and it's stuff like firefox builds that really send /me/ into swap -- not pan because as I said I don't do enough binaries for that to be an issue. Chromium builds were even worse when I was using it, with the various chromium-based webengines near as bad, and libre-office is supposed to be pretty bad as well. But with reasonable tuning I can be double-digit gigs into swap and not even realize it until I happen to glance at my conky memory graphs, while before tuning I was seeing noticeable swap stalls even a couple hundred MB into swap.) -- Duncan - List replies preferred.
