Common questions about ProtonVPN core features, usage tips, and advanced capabilities
VPN Acceler is ProtonVPN's exclusive speed optimization technology, improving VPN connection speed through various technical means. Traditional VPNs are usually 20-50% slower than direct connection due to protocol overhead and single-thread processing. VPN Acceler optimizes these bottlenecks, boosting speed up to 400%.
Traditional VPN clients usually use single-thread for encryption/decryption tasks, unable to fully utilize multi-core CPU performance. VPN Acceler uses multi-thread parallel processing technology, distributing encryption tasks to multiple CPU cores, significantly improving data processing speed, especially effective on high-performance devices.
VPN Acceler deeply optimizes the VPN protocol stack, reducing unnecessary data encapsulation and processing steps. Through optimizing TCP/IP stack parameters, reducing memory copies, using zero-copy technology, it lowers protocol overhead and improves data transmission efficiency.
VPN Acceler includes smart routing algorithms, monitoring network conditions and server load in real-time, automatically selecting optimal paths. Avoids congested network nodes, chooses routes with lowest latency and highest bandwidth, ensuring optimal data transmission paths.
For compressible data types, VPN Acceler uses efficient compression algorithms to reduce transmitted data volume. Through intelligently identifying compressible data (like text, HTML) and already compressed data (like video, images), only compressing compressible data, avoiding repeated compression wasting CPU resources.
VPN Acceler is enabled by default in ProtonVPN client, no manual configuration needed. You can check VPN Acceler status in client settings, temporarily disable if encountering issues. After enabling, connection speed usually improves significantly, especially effective on long-distance connections and high-load servers.
