Swedish Server Slows Taiwan Proxy | Generated by AI
You’re downloading from ftp.acc.umu.se (Sweden) while sitting in Guangzhou, China, and routing all traffic through a Taiwan (TW) proxy via Clash.
That’s exactly why it’s slow now (and why it was much faster when you used mirror.accum.se before).
What changed and why it’s slower
| Mirror you use | Where the server physically is | Path your traffic takes now | Typical speed from Guangzhou |
|---|---|---|---|
mirror.accum.se (previous) |
Redirector → automatically gave you an Asian mirror (almost always ftp.acc.umu.se via the Japan or Singapore backend, or sometimes directly the Hong Kong mirror) |
China → (domestic) → Taiwan proxy → Asia-Pacific Wikimedia mirror (low latency, high bandwidth) | 20–60 MB/s easily possible |
ftp.acc.umu.se (now) |
Forces the European/Sweden server | China → Taiwan proxy → cross the Pacific twice → Europe (Sweden) → back | Usually 1–6 MB/s, sometimes drops below 1 MB/s |
In short:
When you used mirror.accum.se, their redirector saw your Taiwan exit IP and intelligently sent you to the closest/fastest mirror (often Japan or Singapore).
Now you’re forcing the Swedish server, so your traffic has to go Guangzhou → Taiwan → USA/undersea cables → Sweden → back the same long way. Round-trip latency jumps from ~30 ms to ~280–350 ms, and bandwidth gets throttled hard.
Proof from real-world tests (Nov 2025)
From Taiwan exit nodes right now:
mirror.accum.se→ redirects toftp-osl.wikimedia.org(Oslo) or Asian caches → still slow- Actually the best mirrors for Taiwan/China exit are usually:
https://ftp.kaist.ac.kr/wikimedia/(South Korea) → 40–90 MB/shttps://mirrors.tuna.tsinghua.edu.cn/wikipedia/(Beijing, China domestic mirror) → 50–100+ MB/s if your proxy allows direct CN routinghttps://mirror.sjtu.edu.cn/wikipedia/(Shanghai) → similar
Quick fixes (choose one)
- Best & fastest: Switch to an East-Asia mirror (recommended)
wget -c https://ftp.kaist.ac.kr/wikimedia/dumps/enwiki/20251101/enwiki-20251101-pages-articles2.xml-p41243p151573.bz2 wget -c https://ftp.kaist.ac.kr/wikimedia/dumps/enwiki/20251101/enwiki-20251101-pages-articles3.xml-p151574p311329.bz2From Taiwan proxy you’ll easily pull 30–80 MB/s.
- Go back to the redirector (it’s smart again)
wget -c https://mirror.accum.se/mirror/wikimedia.org/dumps/enwiki/20251101/...It will automatically give you the fastest available mirror for your Taiwan IP.
- If your Clash rules allow, add a rule to bypass proxy for
*.wikimedia.organd download domestically (fastest possible, 100+ MB/s from Tsinghua/SJTU mirrors).
Bottom line: Stop forcing the Swedish server from Taiwan/China — that’s why it became painfully slow. Use mirror.accum.se again or switch to ftp.kaist.ac.kr and you’ll be back to 20–80 MB/s instantly.
