There's no real difference in speed. The difference is in structure - for allows you to initialize, increment, and test, while foreach just increments through a list of items. The following are equivalent: 
foreach (@arr[0..2]) { $_++; }
for (my $i = 0; $i <= 2; $i++) { @arr[$i]++; }

The latter offers more control, but isn't necessary for most looping purposes.
