test(snapshot-perf): Increase iterations to 30

N=10 is not a statistically significant sample size. Generally, N=30
seems to be a rule of thumb for not-too-exotic distributions. Since its
reasonable to assume that snapshot restore times aren't too obscure,
lets go with N=30 and observe stability later.
