Why Is Tor Slow? How to Improve Speed

Several fundamental factors make Tor slower than regular browsing:

• Three-hop routing: Your traffic passes through three 中繼 (entry, middle, exit) before reaching its destination. Each hop adds latency. If 中繼 are in different continents, the added distance is significant.
• 加密 overhead: Tor applies three layers of 加密 (one for each 中繼). While 加密 itself is fast, the handshake process at each 中繼 adds latency.
• 中繼 bandwidth: Tor 中繼 are run by volunteers with varying bandwidth. Your circuit is only as fast as the slowest 中繼.
• Network congestion: The Tor 網絡 has about 6,000-7,000 中繼 serving millions of users. During peak times, congestion slows everything down.
• TCP over TCP problems: Tor uses TCP connections between 中繼, and some traffic (like web browsing) also uses TCP. TCP over TCP can cause performance issues known as "TCP meltdown."

Typical speeds: Regular browsing gets 50-500 Mbps. Tor browsing typically gets 1-10 Mbps. This is the trade-off for anonymity.

Try these methods to improve your Tor browsing speed:

1. Request a new circuit: Click the lock icon → "New Circuit for this Site." This assigns different 中繼 that may be faster. Try several times to find a good circuit.
2. Use 橋接 wisely: 橋接 add a fourth hop, which slows things down further. Only use 橋接 if Tor is blocked in your country. If you don't need 橋接, disable them.
3. Choose the right security level: The "最安全" level disables JavaScript, which actually makes pages load faster (less content to download and render). This is a win-win for speed and security.
4. Avoid peak hours: Tor traffic is highest during European and American business hours. Early morning (UTC) tends to be fastest.
5. Use .onion sites: .onion sites use only 6 hops total (3 from you + 3 from the server) instead of 3 hops + clearnet. Since the entire path is within the Tor 網絡, .onion sites can actually feel more responsive for sites hosted on good infrastructure.
6. Keep Tor 瀏覽器 updated: Each update includes performance improvements. The Tor 計畫 constantly optimizes the network protocol.

For power users and service operators:

• Use a fast VPN with WireGuard: If using VPN + Tor, WireGuard protocol adds less overhead than OpenVPN. Mullvad and ProtonVPN both support WireGuard.
• Disable unnecessary features: In Tor 瀏覽器 settings, disable telemetry, auto-play, and other features that generate unnecessary network requests.
• Use lightweight sites: Sites with heavy JavaScript, large images, and complex layouts load slowly through Tor. Prefer lightweight, text-focused versions of websites.
• For 主機代管: optimize your .onion site - minimize page size, use aggressive caching, compress assets, and consider a static site generator. Your visitors will thank you for fast-loading pages.
• Consider OnionBalance: If you run a popular .onion service, OnionBalance distributes traffic across multiple backend servers, improving speed for all visitors.

If you host a .onion service, your server's performance directly impacts how fast your visitors experience your site. Slow 主機代管 means slow pages, regardless of the Tor 網絡's speed.
