Solana has reduced its target slot time from 400ms to 350ms for the first time since the network launched.The change is the first stage of SIMD-0525, which plans further reductions to 300ms, 250ms and 200ms.Shorter slots are designed to reduce confirmation latency while network resource limits are adjusted proportionally.The remaining stages are targeted for Agave v4.2, although the activation schedule remains tentative.
