Solana has reduced its target slot time from 300ms to 250ms, bringing the network to four targeted slots per second.The faster clock cuts each validator’s four slot leader window from 1.2 seconds to one second.Overall processing capacity remains roughly unchanged because computation and data limits fall as slot duration decreases.The 250ms setting shortens an expected Solana epoch from roughly 36 hours to 30 hours.A final reduction to 200ms would bring Solana to five slots per second, but no mainnet date has been set.
