Ruby in Steel 2 VS 2010

[DDayanov]

On my computer when I run ruby file without Debugging in VS 2010 with RubyInSteel 2 using Ruby 1.9.2 it takes 5 times longer then to run it in command line. Is it normal?

Doesn't sound right ... RiS just runs the file pretty much straight (in fact it does run it from a 'command' line), though it does redirect the IO through to the IDE. So if you have a lot of output, this will slow it down quite a bit.

Are you doing much I/O?

Not input - some output and even if I minimize output it doesn't influence on speed - still 5 times slower.

I've just run a simple test ...

Code:

def fac(n)
if (n == 1) then return 1
else return fac(n-1)*n
end
end

def z(n)
while n > 0
fac(n)
n = n - 1
end
end

t1 = Time.new
(1..10).each do
z(1000)
end
t2 = Time.new
puts t2 - t1


puts "done"

If I run this from the IDE with no debugging, I get about 6 seconds - and about the same from the command line. If I run it with the debugger I get 14 seconds.

Can you try the same code with a crean project?

There is no difference between running Ruby from VS with no debugging and from a command line. VS runs Ruby from a command line anyway: it creates a process and runs cmd.exe which then runs Ruby.
