FAQ - VPS
Q. Why is your VPS so fast?
Our VPS leverages the latest 4th-generation AMD EPYC CPUs, which are not yet commonly used by other providers. This CPU series is renowned for having a large number of cores coupled with extremely high clock speeds, maintaining exceptional performance even in virtualized environments.
The primary reason we specifically utilize 4th-generation and newer CPUs is their compatibility with DDR5 RAM. DDR5 RAM, introduced with these CPUs, significantly outperforms traditional DDR4 RAM in speed and efficiency.
Additionally, our storage infrastructure uses the fastest available SSDs—4th generation NVMe drives—and is backed by reliable partner providers offering large-capacity, unrestricted network bandwidth.
Moreover, our platform fully integrates network sharing, effectively reducing the distance between your applications and the Solana network to zero. Since network speed typically represents the main performance bottleneck, we've constructed and provide a high-speed, optimized Solana network environment to ensure your applications achieve maximum performance.
Q. What are the advantages of VPS? How is it different from a bare-metal server?
Bare-metal servers are ideal for performance-critical usage but have a higher starting cost (minimum €140/month) and are typically available in larger server configurations. Conversely, VPS solutions start from €16/month and are well-suited for lightweight tasks such as proxies, stream subscriptions, and running lightweight scripts.
Our VPS fully utilizes the cloud environment and integrates seamlessly with ERPC’s Direct Shreds network.
- For performance-critical use cases: We recommend a bare-metal server.
- For cost-efficient and lightweight tasks: We recommend VPS.

Q. I want the best possible environment.
The ideal setup combines a dedicated Shreds node with our bare-metal servers. This combination leverages a shared network enabling near-zero latency communication, achieving approximately 0.1ms ping.
For more details, please contact us on our official Discord.
Q. I need latency of at least ~400ms or better.
To achieve latency within approximately 400ms, consider these essential points:
-
Realistic Understanding of Ping Values: Ping values indicate ideal conditions and do not reflect actual latency in streaming communications, which typically experience around 5 times the ping latency. For example, a ping of 100ms across continents realistically results in about 500ms of latency. Thus, infrastructure must be established within the same region to achieve ~400ms latency.
- Typical Ping Value Reference:
- Same network: ~0.1ms
- Private Network Interconnect (PNI): ~0.2ms
- Same data center: ~0.3ms
- Same city: ~1ms
- Neighboring country: ~5–10ms
- Intercontinental: ~100–300ms
- Typical Ping Value Reference:
-
Avoiding the Pitfall of Average Latency: Solana validators are geographically dispersed globally, and the leader schedule changes randomly with each epoch. Relying on average latency to achieve ~400ms is impractical. Instead, you should precisely track validator schedules in your specific region to identify slots with the lowest latency. To consistently achieve minimal latency, infrastructure across all relevant regions is required. Within the same region, data acquisition can occur in tens of milliseconds, with transmission possible in just a few milliseconds.
-
Tracking the Leader Schedule: Continuously monitor the leader validator schedule for your region using the ERPC Leader Slot API (
getLeaderSlots).
It provides real-time data on upcoming leaders, validator geolocations, and reference ping values, allowing you to accurately identify optimal trading slots with minimal latency.
This eliminates the limitations of public data sources such as Solana Beach or native RPC APIs, which have slower update frequencies and lower precision.
Q. How can I achieve zero-block (zero-slot) trading?
Successfully achieving zero-block (zero-slot) trading requires more sophisticated strategies, as follows:
-
Identifying Opportunity Zones: Solana validators are distributed globally, and it is physically impossible to achieve optimal latency for every slot. Therefore, monitor validator leader schedules in the region where your infrastructure is located and identify the most favorable opportunity zones. Deploying infrastructure across multiple regions can also be advantageous. For example, Frankfurt is a key region due to its high validator density, resulting in more frequent leader selection and greater trading opportunities.Use the ERPC Leader Slot API (
getLeaderSlots) to obtain real-time leader schedules, validator geolocation data, and reference ping values with far greater precision than Solana Beach or native RPC APIs. This allows you to predict opportunity zones more accurately and execute near-zero-latency trades. -
Implementing Dedicated Nodes: If you struggle to compete, consider deploying dedicated nodes. Shared nodes experience latency due to traffic from other users, and thus are not recommended. Furthermore, placing your dedicated node within the same network as your application significantly reduces network latency and optimizes performance.
Q. What is the latency like?
Latency varies depending on the measurement method and your specific usage environment. Rather than focusing on exact numerical values, it's crucial to ensure that the latency meets your actual operational requirements.
We offer free trials across all our plans, enabling you to test performance directly in your real-world environment. Additionally, we provide easy-to-use tools in TypeScript and Rust for measuring latency. Feel free to utilize these tools alongside your free trial.
Q. Is this RPC (gRPC, Shreds) faster than others?
We encourage you to try our free trial and compare the performance against other services. If you find our service slower, please let us know the specific conditions and competitors you've compared it against via Discord. We will identify the cause and improve the speed further.
We continually work on improving latency based on customer feedback. If you seek the fastest possible endpoint, please share detailed information with us. Providing specific metrics and comparison conditions against competitors allows us to deliver superior performance. This feedback-driven approach has consistently enabled us to enhance our services.
Q. Which plan offers the fastest performance?
Generally, our highest-tier plan provides the fastest performance due to superior CPUs, higher memory capacities, and robust hardware configurations.
We also offer customized solutions if you require even more powerful servers, but our standard plans are designed to deliver optimal price-to-performance ratios.
We are confident in providing world-class performance at every price level. If you find a faster provider within the same price range, please let us know so we can investigate and make improvements.
Q. Which is the fastest: WebSockets, gRPC, or Shreds?
Aggregated customer feedback consistently ranks the speed in this order:
Shreds > gRPC > WebSockets
If your experience differs, please let us know.
Q. Latency isn't what I expected.
Performance differs significantly depending on the programming language used. Generally, language performance ranks as follows:
Rust > Go > TypeScript (JavaScript) > Python
For detailed comparisons, please refer to:
We strongly recommend Rust if maximum performance is your goal.
Q. Why are dedicated endpoints faster?
Shared endpoints are used by multiple customers who share the same resources. As traffic increases, latency tends to occur. Server resources have physical limits, and the amount of work they can handle is finite. When too many requests arrive at the same time, they must be processed sequentially, which results in slower response times.
Although we take various measures to optimize performance even on shared endpoints, with dedicated endpoints you are the sole user of the resource. This means you are completely unaffected by other users, ensuring consistently stable and fast responses.
In addition, dedicated endpoints provide communication options without TLS, such as HTTP. By skipping the TLS handshake (around 20ms), communication becomes even faster compared to HTTPS.
Q. I want to pay with crypto
