A small Rust JSON-RPC + WebSocket gateway that fronts yellowstone-faithful (of1) and routes `jet*` analytics methods to ClickHouse (jetstreamer data). Standard Solana RPC methods pass straight through; new analytic methods are answered from precomputed jetstreamer aggregates.
Deploy a self-hosted Pyth Hermes price feed API stack (NATS + Beacon + Hermes) on a VPS. Hermes serves Pyth Network's REST/WS price feeds (`/v2/updates/price/latest`, `/v2/price_feeds`, `/ws`) by listening to Pythnet for accumulator messages and to the Wormhole network (via Beacon, a highly-available spy) for VAAs. The recipe builds all three components from source, drops systemd units, and validates `/v2/price_feeds` returns 200.
Deploy an OSS-clean nftables ruleset to any slv-managed host (Hermes, Pythnet RPC, validator, RPC, …). Inventory-driven — mgmt IPs, public ports, and per-port allow lists all come from `~/.slv/inventory.{network}.{role}.yml`, nothing is hardcoded. Atomic + rollback-safe (failed validation restores the previous config) and persistent across reboot. Used by `slv hermes firewall` and `slv pythnet firewall`; the same `cmn/deploy_nftables.yml` playbook works against any inventory.
Run a self-hosted Pythnet RPC node — the application-specific Solana fork operated by Pyth's data providers. Pythnet RPC is what `slv-hermes` reads from for accumulator messages; running it locally completes a fully self-hosted Pyth price feed stack. Recipe handles disk mount, sysctl tuning, Solana 1.14 fork build (with cstdint workaround for modern GCC), identity gen, and systemd. Snapshot fetch + catch-up typically finishes in 10-20 minutes.
Build, configure, and run anza-xyz/jetstreamer + ClickHouse on a dedicated analytics node. Streams Old Faithful CAR archives at multi-million-TPS into ClickHouse so historical Solana data is queryable via SQL (program_invocations, slot_status, pubkey_mentions). Includes hourly backfill timer and a rolling-window retention option.
NIC IRQ 1:1 pinning, NVMe queue limits, RPS/XPS, NIC ring buffer, sysctl (UDP/TCP buffers, swappiness, netdev_max_backlog), THP off, and ulimit nofile=1M for Solana / Shredstream nodes. Reboot is required when NVMe queue parameters change.

Solana validator / RPC throughput is dominated by single-thread instruction performance, so disabling SMT consistently produces higher and more stable performance. Applied during slv v init / slv r init as part of the tuning phase.
Adds nosmt=force to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub and runs update-grub. After reboot, the kernel only schedules on one logical thread per physical core.
ansible/cmn/smt_disable.yml — appends nosmt=force to GRUB and runs update-grub/var/lib/slv/.smt_disabledansible-playbook -i inventory.yml cmn/smt_disable.yml --limit <host>
Sets need_reboot=true only when GRUB actually changed; the orchestrator reboots when needed.
# on the host
cat /proc/cmdline # should contain nosmt=force
lscpu | grep -E 'Thread|Core|Socket' # Thread(s) per core: 1
sudo sed -i 's/ nosmt=force//' /etc/default/grub
sudo update-grub
sudo rm /var/lib/slv/.smt_disabled
sudo reboot
