hey validators, lets make solana faster by enabling xdp. xdp improves turbine packet handling by cutting packet overhead, copies and context switches. more shred propagation headroom = better validator performance under load and more room for solana to scale. add: --experimental-poh-pinned-cpu-core <core> \ --experimental-retransmit-xdp-cpu-cores <core> \ --experimental-retransmit-xdp-zero-copy bnxt_en: --experimental-poh-pinned-cpu-core <core> \ --experimental-retransmit-xdp-cpu-cores <core> \ --experimental-retransmit-xdp-interface <physical_interface> \ extend your systemd service: AmbientCapabilities=CAP_NET_RAW CAP_NET_ADMIN CAP_BPF CAP_PERFMON CapabilityBoundingSet=CAP_NET_RAW CAP_NET_ADMIN CAP_BPF CAP_PERFMON LimitMEMLOCK=2000000000 notes: - dont run poh and xdp on the same physical core - keep poh away from the xdp cores shared L3 / numa domain - validate your actual topology with lscpu -e/hwloc or solanahcl/solanahcl/blob/main/public/topology/ easy rule of thumb: - 7965wx: 24c across 4x ccds -> 6 cores/ccd first ccd: 0–5c, next ccd starts at 6c - 9375f: 32c across 8x ccds -> 4 cores/ccd first ccd: 0–3c, next ccd starts at 4c common xdp-capable drivers: i40e, ixgbe, ice, igc, mlx5_core, mlx4_core, bnxt_en dont use bonded interface with xdp. for broadcom / bnxt_en: dont enable zero-copy. copy mode is the safe path. if you run into "huge page alloc failed", remove the zero-copy flag and set the xdp interface to the physical interface: --experimental-retransmit-xdp-interface <physical_interface> check the ring sizes: it needs to be power of 2 IFACE=$(ip route get 1.1.1.1 | awk '{for(i=1;i<=NF;i ) if($i=="dev") print $(i 1)}') sudo ethtool -g "$IFACE" # if you see values like rx: 511 or tx: 511, thats likely the issue. sudo ethtool -G "$IFACE" rx 512 tx 512 restart and voila, you are not a potato anymore.

Introducing DoubleZero Edge. DoubleZero Edge is a new platform delivering real-time market data to traders and market participants, powered by multicast. Its first feed: raw Solana shreds directly from leaders, delivered over a high-performance fiber network. Infrastructure that levels the playing field for validators and matches traditional trading systems is here. Dive in ↓

Monad Mainnet is now live! 🚀 A next-generation, Ethereum-compatible chain delivering 10,000 TPS. Check it out: app.monad.xyz/ We’re running a validator: monadvision.com/validator/0x…

Aztec just shipped Ignition Chain, the first fully decentralized L2 on Ethereum. 🚀 We’re running Provider #50 with 20 queues for delegations. 🔷Public token sale on dec 2nd: sale.aztec.network/ 🔷 Staking Dashboard: stake.aztec.network/provider… 🔷Info: ignition.aztec.network/

Staker Space was a part of the decentralized launch! its feels great to launch the chain together with a diverse set of sequencers! Contributor and Public Sale is ongoing, after that AVM and after that private smart contracts 💥💥

A new, faster internet is here. DoubleZero’s high-performance global network is now live on mainnet-beta powered by 2Z. Welcome to the world of high-performance networking.

Jito finally got competition, or did they?
