We love helping and experimenting with new flashy things, and @OverclockSol's efforts with their new Mithril client are exactly that.

We've submitted a PR to it, as well as run some benchmarking tests on our spare 9375F in our rack.

prostaking.com Testing Mithril: Overclock’s Solana client on eight CPU cores We put Overclock’s Mithril Solana client through a reproducible 5,320-block replay using eight physical CPU cores. Here are the results, what they mean, and what we are testing next.

Our next experiment and findings: @jump_firedancer currently has a PR to enable native Intel NICs support in an architecture similar to their popular Mellanox support

We’ve tested it, submitted a smol fix, on @solana testnet prostaking.com/blog/native-in…
prostaking.com Native Intel networking on X710: less kernel work, the same 28 CPU cores An Intel X710 voting trial cut validator kernel CPU by 0.02262 core. Total CPU stayed near 28 cores. Configuration, measurements and the submitted filter fix.

Our second experiment continues enabling and measuring AF_XDP zero-copy on @jump_firedancer in @solana testnet

This time, Broadcom P4 series NICs. This required modifying the Linux driver itself

Spoiler: 1+ whole CPU core of savings

prostaking.com Broadcom P4 zero-copy: a voting Firedancer validator using one fewer CPU core Our Broadcom P4 voting setup used 1.052 fewer CPU cores over a measured hour. Operator configs, the two-to-one net-tile change, restart corrections and experimental limits.

Our first experimentation and research blog:
Enabling AF_XDP Zero-copy on an Intel X710 driver, and how that impacts @jump_firedancer performance on @solana testnet

Spoiler: 92.65% reduction in CPU kernel time

We are working on Broadcom NICs next

prostaking.com 93% Less Validator Kernel CPU Time with AF_XDP on an Intel X710 Our Intel X710 AF_XDP setup reduced validator system CPU by 92.65%, or 0.329 core—about 1.1% of a 30-CPU budget. Total CPU stayed near 28 cores. Tested configs, data and limits included.
