Subject: [ruby-core:28112] [Bug #2721] OpenSSL::Random.random_bytes(1) is very slow the first time on Windows

Issue #2721 has been updated by Roger Pack.


with mingw 1.9.x

>> Benchmark.realtime { OpenSSL::Random.random_bytes(1)  }
=> 0.890625
>> Benchmark.realtime { OpenSSL::Random.random_bytes(1)  }
=> 0.0

So a bit slow.

with
ruby 1.8.6 (2009-03-31 patchlevel 368) [i386-mingw32]

>> puts Benchmark.realtime { OpenSSL::Random.random_bytes(1) }
1.03125
=> nil
>> puts Benchmark.realtime { OpenSSL::Random.random_bytes(1) }
0.0

with
ruby 1.8.6 (2009-08-04 patchlevel 383) [i386-mingw32]
>> Benchmark.realtime { OpenSSL::Random.random_bytes(1)  }
=> 0.53125
>> Benchmark.realtime { OpenSSL::Random.random_bytes(1)  }
=> 0.0

this with XP Pro...
