Hi In my machine there is Ruby1.8.6 ,1.9.1 and rails 2.3.2 And I created a new project using Ruby1.9.1 and rails 2.3.2 But when did ./script/about it shows Ruby version 1.8.6 (i386-linux) RubyGems version 1.3.1 Why this happens Thanks in advance Sijo -- Posted via http://www.ruby-forum.com/.

If for example you have ruby 1.9 installed in such a way that ruby19 is the ruby 1.9 interpreter (and irb19 the 1.9 version of irb etc.) then you need to either change the shebang line or invoke ruby explicitly (ie ruby19 script/about) Fred Fred> Thanks in advance > Sijo > -- > Posted viahttp://www.ruby-forum.com/.
Hi
Thanks for your it worked Now to test the performance difference
between Ruby1.9.1 and ruby 1.8.6 with rails 2.3.2 what I did is
Created a rails projects using 1.9.1 and 1.8.6 Then created a model and
migrated it to the db using 1.8.6 Ruby+rails Now from the project
created using the 1.9.1 I just make the model only
Now connected this too to the same db For example my model is
School with only one attribute name Then I open console for both the
versions and gave
School.find :all #This has 8 records
And the result I got is
School Load (0.6ms) SELECT * FROM "schools" #from project
1.9.1
School Load (0.6ms) SELECT * FROM "schools" /3from project
1.8.6
Could you please tell where is the performance difference I cant
understand since it both takes same time How can I measure the actual
performance difference using ruby 1.9.1 with rails 2.3.2 and ruby1.8.6
with rails 2.3.2
Thanks
Sijo

Hi, the performance you''ll see is for Ruby code execution. You can try running the Rails tests or the Ruby spec tests. Also, you can try using Apache Bench with concurrency greater than 4 targeting pages which require more Ruby code execution paths.
