Our new metrics dashboard is live at:
https://t.co/RqVvLmmfyn

Inspired by the work of @maxekaplan in a recent dashboard he shared for @solstrategies , we decided to upgrade our internal dashboards too.

193 nodes on testnet have XDP on now.

Retransmit time plummeting. Once we're done, retransmit will settle at ~400 microseconds.

We finish testnet, then we do mainnet, then we finally do 100M CUs.

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.

DD and @trulyhonestwork treasuries lost about $500 each through $CRT NAV loss

luckily had deployed most of our stables last month

well handled by the 🥕 team and hope they can bounce back

⏳ Early participation matters. In this clip, @trulyhonestwork breaks down how engaging early with The Vault and other stakepools helped them accumulate $V, attract stake, and stay ahead with their validator. Interview hosted by @gaius1337 and @sol_nxxn.

imagine staking with a validator team that isn't this committed to the game

it could never be us

🚨 ATTENTION 🚨

I accidentally bought @SolanaConf tickets the same day im supposed to get married and they cost me $2500 (plane, hotel etc) if anyone wants to go take my place for FREE, it’s going to be at the st John church, her name is Sarah, she’s cute, she likes tennis
