Internal 10 Gbps tests showed over 200% aggregate improvement in download and upload speeds with Talaria.
X-VPN has rolled out a speed upgrade spanning its network and new in-house Talaria protocol. In the company’s internal 10 Gbps tests, Talaria delivered over 200% aggregate improvement in download and upload speeds compared with X-VPN’s previous best-performing protocols.
Alongside higher-bandwidth server infrastructure, X-VPN has improved route selection and how devices and servers process traffic. The changes are designed to make connections more efficient, from initial setup to sustained data transfer.
Expanding Server Capacity to 25 Gbps
X-VPN has introduced servers with 25 Gbps port capacity in the United States and Canada, alongside 10 Gbps infrastructure in Germany, Spain, the Netherlands, the UK, Italy, and Singapore. More than 90% of X-VPN’s VPN traffic in the US and Europe can now be served by 10 Gbps or 25 Gbps infrastructure.
Beyond bandwidth, X-VPN has also upgraded its computing hardware. Its new bare-metal server configurations feature 64 CPU cores and 128–256 GB of memory, providing greater processing capacity to handle simultaneous connections and large volumes of network traffic.
The additional bandwidth and computing resources give X-VPN more headroom to handle demanding traffic loads and support high-throughput connections.
X-VPN’s Speed Tests Show
X-VPN conducted internal speed tests across Windows, macOS, Android, and iOS, with connections originating in Singapore and reaching VPN servers in Singapore, the UK, and the US.
Across the 10 Gbps test configurations, Talaria achieved over 200% aggregate improvement in download and upload speeds compared with X-VPN’s previous best-performing protocols.
For example, in 10 Gbps Windows tests connecting to a Singapore VPN server, median download speed increased from 1,536 Mbps with the previous protocol to 5,706 Mbps with Talaria. In separate 1 Gbps tests measuring speed loss against connections without a VPN, Talaria kept download speed loss below 2% on both Windows and macOS across the tested locations in Singapore, the UK, and the US.
These results reflect X-VPN’s internal testing under defined configurations. Actual performance may vary depending on the device, network environment, and VPN server.
Improving Data Transfers Across Devices
X-VPN has also streamlined its client and server data paths to reduce unnecessary data copying, repeated processing, and resource contention.
On Windows, an upgraded kernel data driver helps improve processing efficiency. On macOS, more balanced multicore scheduling keeps CPU cores productive while reducing competition for shared resources. Android and iOS use larger data batches on supported paths, allowing more information to be processed in each cycle with fewer repeated operations.
On the server side, X-VPN has introduced prefetching, batched writes, and more efficient forwarding for eligible traffic. These techniques reduce repeated processing and data handoffs, helping the system make better use of its computing resources during sustained transfers.
How AI Routing Reduces Unnecessary Connection Attempts
X-VPN’s SmartEntry Adaptive Mesh evaluates available high-capacity entry nodes and network conditions to help select a suitable connection path.
Its AI Routing technology, PrivacyRoute Fabric, prioritizes promising connection candidates in time-limited batches rather than attempting every available server. Once a candidate successfully authenticates, the remaining attempts stop.
This approach reduces unnecessary connection attempts and is designed to help users establish suitable VPN connections with less waiting.
Talaria’s Multi-Channel and Parallel Processing Design
Talaria, X-VPN’s new in-house protocol, is designed to make more efficient use of available bandwidth by reducing repeated work during data transmission.
Instead of placing concurrent application connections into a single shared processing path, Talaria gives each connection its own transport channel. Multiple streams can then be processed independently across CPU cores, reducing competition for processing resources when several applications are active.
Talaria also handles data packets in batches, processing multiple packets in a single operation rather than repeating the same steps for each one. Its processing pipeline separates receiving, decryption, and writing data back into stages that can operate independently.
On supported paths, flow-level forwarding further reduces packet-by-packet processing by reconstructing connection flows and forwarding their data more directly.
“Improving VPN speed involves more than adding bandwidth to servers,” said Julian Kwek, Cybersecurity Engineer at X-VPN. “We also looked at how data moves through the connection, from the device to the server and through the transport protocol. By reducing repeated processing at each stage, we can make better use of the bandwidth already available.”
Beyond Speed: Talaria’s Security Audit and Open-Source Release
Talaria incorporates security mechanisms including TLS 1.3, hybrid post-quantum key exchange, authenticated encryption, and replay protection.
The protocol underwent an independent security assessment by Singapore-based Vantage Point Security, including a white-box source code review and protocol-level penetration test. The assessment identified no security vulnerabilities. Four observations were addressed, with their resolution independently verified by Vantage Point Security. Within the scope and limitations of the assessment, the reviewed design and use of cryptography were also found to align with security best practices.
X-VPN has also open-sourced Talaria under the GNU Affero General Public License v3.0 (AGPL v3). Its codebase is publicly available on GitHub for developers, security researchers, and the wider community to review.
Availability
The speed upgrade covers X-VPN’s Windows, macOS, Android, and iOS applications. Talaria is available to both free and premium users, with supported optimizations and performance varying by platform and network conditions.
