Given that

[
    1 to: 30 do:[:j| 1 to: 30 do:[:k| 1 to: 30 do:[:l| 1 to: 30 do:[:m| 
"nothing" ]]]]
] timeToRun

Takes about 50ms it's clearly not the loop which slows your computation down 
but that unspecified "something". So it asking the question of how to speed 
up the loop is pointless as it only contributes .1% to the entire 
computation. You would be better advised to repost your question and include 
what it actually is you are trying to compute.
