I came across this interesting performance stat. Oscillator performance seems to depend on table size.
Running an oscillator for 1000 seconds -

length:  2 ^ 24 , 
poscil -> CPU: 1.918s
oscili  -> CPU: 3.101s

length: 2 ^ 20
poscii -> CPU: 0.913s
oscili  -> CPU: 2.032s

length: 2 ^ 14 
poscil -> CPU: 0.722s
oscili  -> CPU: 0.860s

This might make sense, if larger tables caused more cache misses.
