Set.insert vs array << x unless array.include?(x)

But is the overhead of converting the Point3d's into arrays and uniq! faster than using a Set?

Who knows ?
Time for you to do another test...

I probably don't know what I am doing, but I ran the following test, and obtained the attached results. I typically use array.push variable, and don't understand the situations when the other examples might be used. Btw, when I applied the other forms to my app, it failed in ways that leave me to believe that those forms are data sensitive. Can anyone explaine to a Ruby beginner what's up?

Code: Select all

t=Time.now
a=[]
100000.times do r=rand(10000)
  a<<r
end
a.uniq!
puts Time.now-t

0.125

Code: Select all

t=Time.now
a=[]
100000.times do r=rand(10000)
  a.push r
end
a.uniq!
puts Time.now-t

0.141

Code: Select all

t=Time.now
a=[]
100000.times do r=rand(10000)
  a.push r
end
puts Time.now-t
