I propose replace all the endless loop do to while true:
NUMBER = 100_000_000
def old_slow
index = 0
loop do
break if index > NUMBER
index += 1
end
end
def new_fast
index = 0
while true
break if index > NUMBER
index += 1
end
end
Benchmark.ips do |x|
x.report("new_fast") { new_fast }
x.report("old_slow") { old_slow }
x.compare!
end
Calculating -------------------------------------
new_fast 1.000 i/100ms
old_slow 1.000 i/100ms
-------------------------------------------------
new_fast 0.655 (± 0.0%) i/s - 4.000 in 6.106470s
old_slow 0.259 (± 0.0%) i/s - 2.000 in 7.707258s
Comparison:
new_fast: 0.7 i/s
old_slow: 0.3 i/s - 2.52x slower
What do you think about it?
