jruby slower I/O than MRI in certain cases
------------------------------------------
Key: JRUBY-6111
URL: https://jira.codehaus.org/browse/JRUBY-6111
Project: JRuby
Issue Type: Bug
Components: Windows
Environment: jruby 1.7.0.dev (ruby-1.8.7-p330) (2011-10-05 a4c297e)
(Java HotSpot(TM) Client VM 1.6.0_24) [Windows 7-x86-java] and
jruby 1.7.0.dev (ruby-1.8.7-p330) (2011-10-05 b188fb2) (Java HotSpot(TM) Client
VM 1.6.0_17) [linux-i386-java]
Reporter: Roger Pack
Hello.
With this code, which reads through a file, does some regex:
https://gist.github.com/1265504
With MRI 1.8.7, windows, times are:
4.46178388595581
6.51960682868958
with jruby:
c:\Temp>j -v
jruby 1.7.0.dev (ruby-1.8.7-p330) (2011-10-05 a4c297e) (Java HotSpot(TM) Client
VM 1.6.0_24) [Windows 7-x86-java]
c:\Temp>j --server morph_mri_wins.rb
5.31399989128113
10.2940001487732
so slower, which I was told to report as a bug :)
On linux jruby --server seems consistently faster than MRI 1.8.x and 1.9.1p243
so maybe it's an ASCII line ending thing?
