G: To balance seeding in qBittorrent without overloading your old hardware, you’ll want to tweak Speed, BitTorrent, and Queueing settings carefully.

---

✅ TL;DR:

• Enable uploading by removing hard limits that prevent idle seeding.
• Cap upload speed globally (e.g., 100 KiB/s max total, not per torrent).
• Limit upload slots per torrent to reduce stress.
• Use “Do not count slow torrents” in queuing so idle torrents still seed.
• Avoid “force start” unless necessary—fix root behavior instead.

---

🔧 Step-by-Step Settings to Adjust

1. Speed → Global Rate Limits

Go to: Tools > Options > Speed

• Upload: Set Global Upload Rate Limit to 100 KiB/s
• Download: You can leave this at 3000 KiB/s or 0 (unlimited)
• Check: ✅ "Apply rate limit to transport overhead"
• Check: ✅ "Apply rate limit to uTP connections"

---

2. Speed → Alternate Rate Limits (Optional)

If you want a “day mode / night mode” (e.g. no upload during the day):

• Enable alternate limits (e.g., 0 upload during 9am–5pm)
• Otherwise, leave disabled.

---

3. BitTorrent → Connections

Go to: Options > BitTorrent

• Global maximum connections: 100–200
• Maximum connections per torrent: 30–50
• Upload slots per torrent: 2–4
• ✅ Enable uTP, DHT, PEX, and Local Peer Discovery
• This keeps your device from being swamped while allowing uploads.

---

4. Queueing

Go to: Options > Queueing

• ✅ “Enable Torrent Queueing”
• Maximum active downloads: 1–2
• Maximum active uploads: 2–3
• Maximum active torrents: 3–5
• ✅ "Do not count slow torrents"
  • This lets seeding torrents keep trying even if they're quiet.

---

5. Behavior to Check

• Right-click each torrent and ensure “Limit upload rate” is unchecked unless you want per-torrent limits (not recommended with your setup—use global limits instead).
• Don’t use Force Start as your default—fix seeding logic so torrents start normally.

---

🧠 FYI

Older systems often stall if:

• Too many active connections
• Disk cache isn’t set up well
• You're writing and reading at the same time (e.g. downloading while uploading heavily)

If the above tweaks still cause sluggishness, reduce:

• Global connections to 80
• Upload slots to 2
• Simultaneous torrents to 2

---

Let me know your specs if you'd like help with buffer/cache settings to reduce disk stress.

G: qBittorrent does not have built-in support for dynamic seeding prioritization based on recent activity, like “no activity in 15 minutes → move to bottom of queue.” But here’s what can be done, along with some practical workarounds and semi-automated options.

---

🟥 qBittorrent Built-in Limitations

• No “activity-based reordering” of torrents.
• No automatic demotion of idle torrents.
• Only prioritizes torrents based on queue order and simple max active rules.
• You can right-click and manually prioritize or resume specific ones, but this doesn't scale well.

---

✅ Workarounds Within qBittorrent

1. Enable "Do Not Count Slow Torrents"

Options > Queueing → ✅ Do not count slow torrents

This lets new torrents get a chance to activate even if the max upload slots are full, as long as some of those uploads are slow (idle or near-idle).

🔹 Definition of "slow":
qBittorrent uses an internal threshold (usually <1 KiB/s for several minutes). It’s not exactly 15 minutes, but it helps bypass frozen uploads.

---

2. Queue Tweaks

Set:

• Max active uploads: 2 or 3
• Max total active torrents: e.g., 5 or 6
• Enable queueing and order the torrents how you want

The slow ones will gradually drop out if they get no activity, letting others try.

---

🛠️ External Automation Option (Advanced)

If you're willing to script, you can use the qBittorrent Web API to:

1. Periodically scan your torrents' activity.
2. Pause any seeding torrent with no upload activity in 15+ minutes.
3. Resume a different paused torrent to test its activity.

You’d use something like:

• GET /api/v2/torrents/info?filter=seeding
• Check each torrent’s upspeed or last upload time
• Pause it via POST /api/v2/torrents/pause
• Resume another via POST /api/v2/torrents/resume

This would act like a “rolling seeder test.”

Want a starter script in Python or shell?

---

🟨 Third Option: Manual Re-Prioritization Script

If you don’t want full automation, but can run a script daily or weekly, a lighter solution:

• Sort all torrents by “Last Activity” or “Uploaded” (right-click the column bar to show it)
• Create a one-click script to pause all torrents with zero upload and last activity > 24 hours
• Resume a handful of paused torrents not recently tried

It’s still semi-manual, but scalable with batch tools.

Summary

Goal	Best Option Available
Automatic queue demotion	❌ Not built-in
Prioritize active uploads	✅ Use "Do not count slow torrents"
Avoid resource overload	✅ Tune queueing + upload limits
Dynamic testing of idle torrents	🛠️ Write a script using Web API

Let me know if you want a minimal script that cycles seeding torrents based on activity.
