PERSISTENT_THRESHOLDS(1so)

📦 version 3.2_p4, in alpine 3.24, nixos 26.05, nixpkgs unstable

🎀 PERSISTENT_THRESHOLDS 🎀

okay so this is PERSISTENT_THRESHOLDS from the 1so manual section, and bestie, it is short — but it's also kind of a chaotic read, so let's unpack it together. 🫶

These settings control the behavior of in granting and dropping persistent tcp connections. ✨ (yes, that's the sentence — we're keeping it exactly like that, iykyk.)

The default settings are the ones shown. In general no changes should be needed — like, genuinely, you can probably leave these alone and go touch grass. 🌸 And in general the purpose is to limit total resource usage from an errant or rogue client. 💅

okay so here are the knobs, one by one:

  • Minimum seconds that a persistent tcp connection to is kept open. — it's the minimum seconds a persistent tcp connection to is kept open, and this is the limit used when the number of connections is above. 🔥 (yep — the page just says above and then stops. that's how it came, so that's how it stays 🙈)
  • Maximum seconds that a persistent tcp connection to is kept open. — the maximum seconds a persistent tcp connection to is kept open, and this is the limit used when the number of connections is below. ⭐
  • Maximum number of persistent tcp connections to — the max number of persistent tcp connections to, before connections start getting the more stringent time limitation. 💀 (that "more stringent time limitation" is the strict one, so like, heads up.)
  • Maximum number of persistent tcp connections to — the max number of persistent tcp connections to, before no more are allowed (only non-persistent at this point). 👑
real talk: that last line — "before no more are allowed (only non-persistent at this point)." — appears twice back to back on the original page. not me fixing it, because the rule is every detail stays, so we're keeping the encore. 🫶 like, iconic that it said it twice.

and that's the whole page, bestie — PERSISTENT_THRESHOLDS from the 1so manual, no version or date line came along with it, so consider this your cute little sign-off. go forth and limit that total resource usage from errant or rogue clients. 🌈💖
