Benchmarking it on my machine shows the multi line version running faster than the one liner.
use Benchmark;

@array = ('elementary school', 'blah blah blah', 'stuff', 'hello', 'ya
+y');

timethese(100000, {
    'one line' => '&one_line',
    'multi line' => '&multi_line'});

sub one_line
 {
   do {s/\s+/\t/; s/elementary/my dear Watson/g;} for @array;
 }

sub multi_line
 {
   for ( @array ) {
       s/\s+/\t/;
       s/elementary/my dear Watson/g;
   }
 }

Output:
multi line: 5 wallclock secs ( 5.04 usr + -0.01 sys = 5.03 CPU) @ 19880.72/s (n=100000)
one line: 5 wallclock secs ( 5.72 usr + 0.00 sys = 5.72 CPU) @ 17482.52/s (n=100000)
