Ironruby core - Jun 2008 - Performance difference in Asp.Net with IronRuby.

Hi,

Will there be any significant difference between Asp.Net with C# and
IronRuby.?

Since i have ready many blogs claiming C# to be running faster than
Vb.Net, i just wanted to reconfirm that will IronRuby at par with C# or
Vb.Net.

I am more confused about performance since C# runs directly on CLR
and...
IronRuby runs on DLR, which itself runs above CLR.

Let me make more clear.

C#
--------
Runs on DLR  ---------Only one layer.

IronRuby
----------
DLR
---------
CLR   --------------Two layers.

Sorry for my newbie question.

This question applies to IronRuby final RTM

Thanks

This question pre-supposes that the speed of the language is the most
important factor in the performance of a web-site, an assertion I believe to
be contrary to most evidence and experience.

Agreed, unless you are running high performance computing applications, like
number crunching, your code will probably be slowed down by I/O, Database or
other external factors. As far as performance, it isn?t a major concern for us
yet. We are more focused on being compatible with RubySpec and CRuby. We will be
involved in the Ruby Benchmark Suite project
(http://antoniocangiano.com/2008/06/01/help-me-create-the-ruby-benchmark-suite/),
and will focus on those benchmarks when the time comes. I?d say a better
comparison would be ?will we be at par with JRuby or CRuby? and we hope to be on
par with JRuby eventually.

Sidenote: Can anyone give some links on those blogs (VB vs C#) they are both
compiled to IL, so I don?t see why one would be faster, just curious.

It was true, early in .NET, that the C# compiler was a more aggressive
optimizer than the VB.net compiler. Not sure if it''s still true or not.

Ah. Didn?t know that.

Thanks!

I''ve seen a couple suggestions on blogs that suggested C# was faster
than
VB.NET, but when it came down to testing, either the code wasn''t
directly
equivalent or the performance difference was fairly negligible.

If someone has something to suggest otherwise, I''d be interested in
that
too.

Performance is a very complex issue. I suggest that everyone reads Joseph
Newcomer article "Optimization: Your Worst Enemy"

For pure computational speed, VB and C# are equivalent to each other and will be
much faster than IronRuby.

Whether you see the performance difference in real code will depend on where the
bottleneck in your application is. For web application, it is highly unlikely
that your app''s perceived performance will bottleneck in the code that
renders HTML. It is far more likely the case that you''ll bottleneck on
your database or some other shared resource.
