Peaks decide, not monthly totals. The arithmetic for both port speeds, why one connection rarely fills 10 Gbit/s, and which workloads justify the faster berth.

**Quick answer — Do I need a 1 Gbps or 10 Gbps port on my server?**

You need a 10 Gbps port only if your server often has to push more than 1 Gbit/s at once. Typical cases are mirrors, large restores and busy VPN or Tor traffic. Otherwise a 1 Gbps port, good for 324 TB in 30 days, is enough. **Ravenquay** sells both unmetered: Harbor 8 at $72.62, Harbor 10G at $356.25. No KYC; crypto only.

## How do a 1 Gbps and a 10 Gbps port compare?

|  | 1 Gbit/s port | 10 Gbit/s port |
| --- | --- | --- |
| Bytes per second at full speed | 125 MB | 1.25 GB |
| Most data in 30 days, each direction | 324 TB | 3,240 TB |
| Time to send 1 TB at full speed | 2 h 13 min | 13 min 20 s |
| Time to send 10 TB | 22 h 13 min | 2 h 13 min |
| Time to send 100 TB | 9 days 6 h | 22 h 13 min |
| Clients at 25 Mbit/s each, all at once | 40 | 400 |
| Data one TCP flow must keep in flight at a 50 ms round trip | 6.25 MB | 62.5 MB |
| Ravenquay berths | Harbor 8 (8 cores / 16 threads), Harbor 16 (16 cores / 32 threads) | Harbor 10G (24 cores / 48 threads) |
| Price per 30 days, unmetered | $72.62 or $205.27 | $356.25 |

Line-rate arithmetic in decimal units (1 TB = 10^12 bytes), before protocol overhead. A calculation, not a measurement.

## When is a 1 Gbps port enough?

A 1 Gbps port is enough when your busiest minutes stay below about 800 Mbit/s. The monthly total matters far less than the peak.

The arithmetic is generous. A port that averages 300 Mbit/s still moves about 97 TB in 30 days. Workloads that usually fit:

- a website, an API or a shop with steady traffic;
- a WireGuard or OpenVPN server for a team or a family;
- a Matrix homeserver for a community;
- a Tor middle relay or bridge;
- build, test and staging machines.

**Ravenquay surveyed 18 no-KYC crypto hosts on 30 October 2026: 11 sold an unmetered dedicated server, but only 4 did so at 10 Gbit/s.** The full conversion from speed to volume is on [how many TB a 1 Gbps port transfers per month](https://ravenquay.com/1gbps-to-tb-per-month/ "1 Gbit/s to terabytes, with protocol overhead").

## When does a 10 Gbps port pay off?

A 10 Gbps port pays off when many clients pull data at the same moment, or when a large transfer has a deadline.

- **Public download mirrors** for open-source projects, where hundreds of machines fetch the same release on the same day.
- **Backups and restores.** Restoring 10 TB takes about 2 hours and 13 minutes at 10 Gbit/s, against more than 22 hours at 1 Gbit/s.
- **A VPN service** with hundreds of users online together; see [how to start your own VPN service](https://ravenquay.com/start-your-own-vpn-service/ "Running a VPN business on rented servers").
- **Tor relays** running several instances on one machine; see [Tor exit sizing at 1 and 10 Gbit/s](https://ravenquay.com/tor-exit-relay-bandwidth/ "Tor exit traffic on 1 and 10 Gbit/s ports").
- **Origin servers** feeding your own cache or CDN, and dataset transfers between datacenters.

**A 10 Gbit/s port does not make one download ten times faster; it lets ten times as many run at full speed.**

## Why can one download not fill a 10 Gbps port?

Because a single TCP connection can only send what its window allows in each round trip. RFC 7323 states that TCP performance problems arise when the bandwidth × delay product is large.

To fill 10 Gbit/s on a 100 ms path, one flow needs 125 MB of data in flight. On a 20 ms path inside Europe it still needs 25 MB. The Linux kernel documentation sets the default ceiling for automatically tuned send buffers between 64 KB and 4 MB, depending on RAM.

**With a 4 MB send buffer and a 100 ms round trip, one TCP flow tops out near 335 Mbit/s.** A faster port does not change that. That figure is an upper bound from arithmetic, not a measurement.

Two fixes exist. ESnet's guide for hosts with a 10G network card raises the buffer ceilings to 32 MB and 64 MB. For bulk transfers, it notes that tools such as Globus open 4 to 8 parallel streams.

*/etc/sysctl.d/90-10g.conf: ESnet's values for a 10G host, paths up to 100 ms*

```ini
net.core.rmem_max = 67108864
net.core.wmem_max = 67108864
net.ipv4.tcp_rmem = 4096 87380 33554432
net.ipv4.tcp_wmem = 4096 65536 33554432
net.core.default_qdisc = fq
```

Load the file with `sysctl --system`. ESnet advises leaving the congestion control at its default, which is CUBIC on most Linux distributions.

## What else has to keep up with a 10 Gbps port?

Everything between the disk and the far end. A 10 Gbit/s port only helps when each link in that chain is as fast.

- **Storage:** serving files at full speed means reading 1.25 GB every second, from the disks or from memory.
- **CPU:** TLS and VPN encryption cost processor time per packet. Harbor 10G has 24 cores / 48 threads and 128 GB DDR5 ECC. Tunnel throughput is covered on [how fast WireGuard is on a 10 Gbps server](https://ravenquay.com/wireguard-10gbps-throughput/ "WireGuard speed on a 10 Gbit/s port, from published sources").
- **Software:** a single-threaded server process can saturate one core long before the port.
- **The far end:** each client receives no faster than its own connection allows.

## How do I find out which port my server needs?

Measure the busiest five minutes of a normal week, not the monthly total. Three standard Linux tools are enough:

- `vnstat -l` shows the live rate on an interface, and `vnstat -5` keeps 5-minute history.
- `sar -n DEV 1` prints the rate of every interface once per second.
- `ip -s link` shows the raw byte counters, so you can compute a rate yourself.

If your peaks often pass 800 Mbit/s on a 1 Gbit/s port, the port has little headroom left at busy times. That is the moment to move to 10 Gbit/s.

## Which Ravenquay berth matches each port speed?

Harbor 8 and Harbor 16: Unmetered at 1 Gbit/s. Harbor 10G: Unmetered at 10 Gbit/s. Unmetered means no monthly traffic quota and no overage bill: the port speed of your plan, 1 or 10 Gbit/s, is the only limit. Each server has one dedicated IPv4 address and an IPv6 /64. Terms and every price are on the [Ravenquay pricing page](https://ravenquay.com/pricing/ "Ravenquay berths and prices per 30 days"). The 10 Gbit/s berth has [its own page, with the hosts it is priced against](https://ravenquay.com/10gbps-unmetered-dedicated-server/ "Harbor 10G, unmetered 10 Gbit/s").

| Plan | Quantity | 30 days | 3 months | 6 months | 1 year |
| --- | --- | --- | --- | --- | --- |
| Harbor 8 | 8 cores · unmetered 1 Gbit/s | $72.62 | $196.07 (−10%) | $348.57 (−20%) | $610 (−30%) |
| Harbor 16 | 16 cores · unmetered 1 Gbit/s | $205.27 | $554.22 (−10%) | $985.29 (−20%) | $1,724.26 (−30%) |
| Harbor 10G | 24 cores · unmetered 10 Gbit/s | $356.25 | $961.87 (−10%) | $1,710 (−20%) | $2,992.50 (−30%) |

In every plan: Unmetered port · Tor exits allowed · RAID 1 · Dedicated IPv4 · No logs · No KYC

**Before you pay**

- Minimum top-up $1. Top up once in crypto, then buy any plan from your balance.
- Credit on your balance does not expire and renews any of your servers. When a top-up is only made to reach the minimum, the unspent part comes back on request within 30 days of payment, in USDT or USDC. The rest of a balance is not paid out unless the law requires it.
- Credited once your payment is checked on the blockchain. Typical network confirmation time: BTC ≈ 20 min · USDT TRC-20 ≈ 1 min · USDT ERC-20 ≈ 5 min · USDC ERC-20 ≈ 5 min · ETH ≈ 5 min · SOL ≈ 1 min · LTC ≈ 15 min · XMR ≈ 20 min

## What do buyers ask about port speed?

### Is 1 Gbps enough for a dedicated server?

For most single websites, team VPNs and community services, yes. A 1 Gbit/s port serves 40 clients at 25 Mbit/s each at the same moment, and can move 324 TB in 30 days.

### How fast is 10 Gbps in MB/s?

1,250 MB per second at line rate, in decimal megabytes. After Ethernet and TCP/IP headers, a single direction carries roughly 1,180 MB of file data per second.

### Will a 10 Gbps port make my own download faster?

Only if your own connection and the path allow it. A single TCP flow is limited by its window and the round-trip time, so one remote download often stays far below 10 Gbit/s.

### Do both Ravenquay port speeds follow the same traffic rule?

Yes. Unmetered means no monthly traffic quota and no overage bill: the port speed of your plan, 1 or 10 Gbit/s, is the only limit. Each server has one dedicated IPv4 address and an IPv6 /64.

### How much more does 10 Gbit/s cost at Ravenquay?

Harbor 10G costs $356.25 per 30 days, against $72.62 for Harbor 8 and $205.27 for Harbor 16. There is no setup fee: you pay the price of your chosen term, both when you order and when you renew.
