Solana Gradually Cuts Slot Time From 400ms to 250ms

The Solana Foundation said it has gradually reduced slot time from 400ms to 250ms, continuing toward a 200ms target, with skip rates staying stable and low with no clear correlation to the reduction. Network "stall time" from consecutive skipped slots fell from over 1,800ms to about 1,200-1,400ms, and the p99 window for a single validator controlling transaction ordering fell from about 3 seconds to 2. Vote latency rose, especially for Asian and South American nodes, so cutting further to 200ms before Alpenglow still requires caution.
