23/ Correction: the block-time numbers shown earlier were actually shred spread. With real block-time data, only Frankendancer Harmonic BAL and Frankendancer Harmonic PRF run over 400ms. All other schedulers, including Agave @Rakurai_io and Agave @harmonic_gg, sit below.

On @solana, execution at the scheduler level directly determines outcomes. @syndica's latest Solana report (April ’26) focuses on transaction packing, CU composition, and block timing efficiency across the client landscape. This is exactly where Rakurai stands out 🧵
