The deployment expands a proof-of-concept previously limited to the New York region to the full infrastructure across all regions. The XDP fast path and AF_XDP zero-copy reduce kernel overhead in the Turbine shred propagation and ingestion path, shortening stream delivery lag for Geyser gRPC and improving state freshness for RPC queries. ERPC applied the optimization to both RPC nodes and Geyser gRPC source nodes. The deployment uses the startup flag system reorganized in Agave 4.1, with per-region configuration. ERPC noted that enabling XDP requires a new kernel, XDP-capable NIC, appropriate systemd capabilities, correct startup flags, and proper CPU core pinning, and that deploying across all regions increased operational difficulty. The operational expertise is consolidated into the open-source Solana operation tool SLV as reproducible recipes. ERPC offers hourly billing starting from 1 hour and supports Crypto Pay with SOL, USDC, or EURC.","whyItMatters":"By extending kernel-bypass networking from a single-region proof-of-concept to all production nodes, ERPC has made a latency optimization that was previously experimental into a baseline feature available to every customer regardless of region.","webCardHtml":"\u003cp\u003eERPC\u0026#39;s own ASN (AS200261) granted by RIPE NCC places source nodes, receiving endpoints, and processing nodes within premium data centers where Solana validators are densely concentrated. The company states that software optimizations like XDP and zero-copy achieve maximum effectiveness only on top of this physical and network proximity design.\u003c/p\u003e\n\n\u003cp\u003eAnza introduced XDP for Turbine in Agave 3.x (v3.0.9 and later) and carried it into Solana v4 (Agave 4.x). According to Anza\u0026#39;s setup guide, using XDP can push outgoing packets to nearly 150,000 per second for large validators due to Turbine fanout. In Agave 4.1, the startup flags were reorganized: --experimental-retransmit-xdp-* flags were deprecated and replaced with --xdp-interface, --xdp-cpu-cores, and --xdp-zero-copy.\u003c/p\u003e\n\n\u003cp\u003eThis full regional deployment follows a lineage of infrastructure enhancements: the December 2025 full regional Geyser gRPC infrastructure upgrade, the January 2026 large-scale Frankfurt (FRA) region enhancement, and the June 2026 New York (NY) region\u0026#39;s early adoption of XDP and zero-copy.\u003c/p\u003e\n\n\u003cp\u003eFor verification, ERPC provides open-source benchmark tools. Use slv check geyserbench --kind grpc for first-arrival comparisons on Geyser gRPC, and slv check grpc for individual endpoint connectivity and latency checks.
