I run servers that do stuff

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.

@adlonymous @faremeterxyz returns all the data you need in the extra field so clients don't need an rpc connection

@durov This seems a bit cherry picked gng

@jarxiao @toly @solana How did this Happen? Did they censor prop amm oracle updates in the prior blocks?

[Sam Altman @sama]

we still get looksmaxxed on frontend a little but we IQmog hard now

[Splatter @SplatterSOL]

why. in 2026. does your webiste show me a phantom login popup each time I click something..

[DoubleZero @doublezero]

Market data over the internet works.

Solana shreds over DoubleZero Edge wins.

DoubleZero Edge beta is live. ↓

@bencirc @colosseum yeah okay, so custom handlers for every program

@cavemanloverboy ty

[Splatter @SplatterSOL]

@sonic_from_ny for sure. and for some amms it's a huge difference. Bisonfi almost has a 50% CU reduction for swaps when this goes live. Though the majority of amms aren't nearly as "cheap" as bisonfi

[Splatter @SplatterSOL]

its cool that token program cu is decreasing.. But the majority of CU in defi swaps aren't from the token program atm

[Splatter @SplatterSOL]

@SolPlay_jonas Ohhh, nice. I was actually looking at this yesterday and couldn’t find a nice way to integrate kit with my anchor stuff
