New users who have just started using Hong Kong CN2 cloud servers may find it confusing to choose between the two options: 10 Mbps dedicated bandwidth and 100 Mbps shared bandwidth. Their prices can be comparable, and the 100 Mbps shared package may even cost less. This article breaks down the core differences between 10 Mbps dedicated and 100 Mbps shared bandwidth, and helps you pick the suitable option for your business.
Dedicated bandwidth means the bandwidth resource is exclusively allocated to your server alone. To draw an analogy: it is like an independent water pipe installed exclusively for your household. No matter how much water neighboring households consume, the water flow at your tap remains stable at all times. A 10 Mbps dedicated bandwidth plan guarantees you a consistent throughput of up to 10 Mbps (approximately 1.25 MB/s) around the clock, completely unaffected by other tenants.
Shared bandwidth refers to a total pool of bandwidth resources shared by dozens or even hundreds of VPS instances hosted on a single Hong Kong physical server. This is comparable to a main water pipeline supplying an entire apartment building, with every household drawing water from the same trunk line. During daytime off-peak hours when fewer users are online, the connection speed will be fast; yet during evening rush hours when everyone streams media or downloads files, the bandwidth will become extremely constrained. A 100 Mbps shared plan means you share a combined total bandwidth of 100 Mbps with dozens of other tenants. You may achieve high throughput when traffic is light, but speeds could drop below 5 Mbps during peak hours.
Core Comparison: 10 Mbps Dedicated Bandwidth vs 100 Mbps Shared Bandwidth
| Comparison Metric | 10 Mbps Dedicated Bandwidth | 100 Mbps Shared Bandwidth |
| Stability | Consistent throughput with zero fluctuations all day long | Severe speed throttling during peak hours; fast speeds only at off-peak times |
| Maximum Throughput | Permanently capped at 1.25 MB/s | Over 10 MB/s during off-peak periods; may drop below 1 MB/s in rush hours |
| Applicable Scenarios | Corporate official sites, e-commerce stores, database services, remote office work | Personal testing environments, file download sites, off-hours data backup tasks |
| Pricing | Generally higher cost | Cheaper; often advertised as unlimited data transfer |
| Oversubscription Risk | None, with physical resource isolation | Extremely high; providers may allocate a single 100 Mbps pool to over 200 users |
Why 100 Mbps Shared Bandwidth Is Often a Hidden Pitfall
Many service providers take advantage of novice users’ misconception that higher bandwidth numbers equal faster connections, and aggressively market 100 Mbps shared packages. However, the real-world performance frequently falls short of 10 Mbps dedicated bandwidth.
A common deceptive tactic: a single physical server hosts 50 separate VPS instances, each labeled "100 Mbps bandwidth", while the total outbound port capacity is merely 200 Mbps. During peak hours, all 50 servers compete for the same 200 Mbps pool, resulting in an average allocation of only 4 Mbps per instance. Some unethical providers go even further by enforcing strict QoS traffic shaping on each VPS. Despite the "100 Mbps" label, permanent hard limits cap actual throughput below 30 Mbps.
Simple Method to Identify Shared Bandwidth Oversubscription
Run a speed test once in the afternoon, then repeat the test at 9 PM. If evening throughput falls to less than one-third of daytime speeds, the shared bandwidth pool is heavily oversubscribed.
Which Option Should You Choose? Match the Bandwidth to Your Business Needs
Scenarios Where 10 Mbps Dedicated Bandwidth Is Always Recommended
1. Corporate official websites & cross-border e-commerce stores: Stable connectivity is critical. Visitors will not wait for slow-loading product pages a second time.
2. API endpoints & database servers: Minor bandwidth jitter causes request timeouts and failed data synchronization.
3. Remote office work & code repositories: SSH connections and Git cloning demand steady, uninterrupted links; intermittent disconnections drastically reduce work efficiency.
4. Video conferencing & real-time audio/video streaming: Latency fluctuations on shared bandwidth lead to constant freezing and buffering.
Scenarios Where 100 Mbps Shared Bandwidth May Be Considered (Only for Extremely Tight Budgets)
1. Personal development testing & learning environments: Minor lag during code execution or command-line operations is acceptable.
2. Off-hours backup & data migration: Automated data synchronization scheduled at 3 AM leverages idle shared bandwidth for decent transfer speeds.
3. Static small-file download platforms: Suitable if your users primarily download lightweight files with low sensitivity to transfer speeds.
Scenarios Where 100 Mbps Shared Bandwidth Must Be Avoided Entirely
1. Public-facing websites: Evening peak hours coincide with your highest visitor volume; server slowdowns will drive potential customers away.
2. Live streaming & real-time game servers: Packet loss and variable latency will drive all users away instantly.
3. Video streaming platforms & online education services: Persistent buffering and lag cause immediate user exits.
Three Undisclosed Truths Providers Hide from Customers
1. "Peak 100 Mbps" does not equal "Guaranteed 100 Mbps"
The term "peak" only refers to the theoretical upper limit, not sustained available bandwidth at all times. The key metric to prioritize is guaranteed or dedicated bandwidth.
2. "Unlimited data transfer" on shared bandwidth is a misleading trap
Unmetered traffic plans operate on severely constrained shared ports. Even with a 1 Gbps shared port label, continuous high-volume transfers trigger aggressive throttling down to a few megabits per second.
3. Real-world performance of 10 Mbps dedicated bandwidth far outperforms 100 Mbps shared bandwidth
Real test case: After migrating from a 100 Mbps shared server (less than 5 Mbps throughput at night peak) to a 10 Mbps dedicated server, the homepage load time of an e-commerce site dropped from 8 seconds to 1.5 seconds.
Verification Steps Before Purchasing
1. Request a test IP from the provider and run file download speed tests via `wget` to record baseline throughput.
2. Complete two rounds of testing: one at 3 PM and another at 9 PM, then compare results.
3. If evening speeds drop by over 50% compared to afternoon speeds, reject the package outright.
Post-Purchase Bandwidth Validation
Use `iperf3` with public speed test servers to verify actual allocated bandwidth. Sample command:
iperf3 -c speedtest.server.com -p 5201 -P 4For nearly all production-grade business workloads, 10 Mbps dedicated bandwidth vastly outperforms 100 Mbps shared bandwidth. Do not be misled by large numerical labels; stable connectivity is the core lifeline of server bandwidth. Shared low-cost bandwidth suffices only for casual personal experimentation. If you operate formal websites or commercial services, always opt for dedicated bandwidth—even a 5 Mbps dedicated plan is far more reliable than a 100 Mbps shared pool. Remember: consistent server performance retains your visitors and customers.
