Solana Cuts Slot Time to 250ms in Latest Speed Upgrade
Solana has made significant strides in improving its network speed by reducing its target slot time from 300 milliseconds to 250 milliseconds. This change, which went live on September 18, increases the rate at which the network produces slots by nearly 17% without raising its overall processing ceiling.
The new setting brings Solana to four targeted slots per second, compared with roughly 3.3 under the previous 300ms configuration. This reduction in slot time is part of the SIMD-0525 upgrade, designed to gradually reduce slot times from the network's original 400ms setting to a final target of 200ms.
Solana validators continue to serve as leaders for four consecutive slots. With each slot now targeted at 250ms, a validator's nominal leader window has fallen from 1.2 seconds at the previous setting to one second.
