Not faster. Blockchain difficulty is always adjusted so that each block happens in nearly regular intervals. For BTC it is 10 minutes, for LTC it's 2.5 minutes and for ETN it's 2 minutes. The block time interval is fixed. It can't be faster.
Got it, than the reverse assumption. Can it be slower than in case a network drops 100x, 1000x or fictional 10,000 times?
