Solana cut its target slot time from 300 milliseconds to 250 milliseconds earlier Friday, blockchain data shows, making the network’s clock run nearly 17% faster without producing an equivalent increase in total transaction capacity. Imagine a railway station at a major financial hub. On Friday, the station cut the wait time between trains to 25 seconds from, say, 30 seconds. A single train still carries the exact same number of people and the total number of people moving through the station per hour remains the same.
