Intenté lo siguiente:
def measure(t)
single_measures = []
double_measures = []
double_quoted_string = ""
single_quoted_string = ''
single_quoted = 0
double_quoted = 0
t.times do |i|
t1 = Time.now
single_quoted_string << 'a'
t1 = Time.now - t1
single_measures << t1
t2 = Time.now
double_quoted_string << "a"
t2 = Time.now - t2
double_measures << t2
if t1 > t2
single_quoted += 1
else
double_quoted += 1
end
end
puts "Single quoted did took longer in #{((single_quoted.to_f/t.to_f) * 100).round(2)} percent of the cases"
puts "Double quoted did took longer in #{((double_quoted.to_f/t.to_f) * 100).round(2)} percent of the cases"
single_measures_avg = single_measures.inject{ |sum, el| sum + el }.to_f / t
double_measures_avg = double_measures.inject{ |sum, el| sum + el }.to_f / t
puts "Single did took an average of #{single_measures_avg} seconds"

puts "\n"
end
both = 10.times do |i|
measure(1000000)

Si no me equivoqué, me parece que ambos toman aproximadamente el mismo tiempo, a pesar de que las citas simples son ligeramente más rápidas en la mayoría de los casos.
