Subject: ruby performance

Hi,

I have snippet from my project, and this iteration is performing very
very badly compared to same implementation in Java

Java : Time Elapsed in milliseconds: 8109 ms.
Ruby : Time Elapsed in Seconds: 132.28125 sec.

It a huge difference, Am i missing something here, is there any
particular best practices.  I am trying to implement Ruby for a
particular project, where it needs to read/process huge arrays etc
 Please guide me.

input = "ababaa" * 10000
suffix_array = input.split(//)
suffix_array_len = suffix_array.size

for i in 1..suffix_array_len-1 do
  total=0
  for j in i..suffix_array_len-1 do

  end
end
