Hi! Is it just me, or is installing gems with IronRuby extremely slow? (at least compared to other Ruby platforms, like JRuby) It seems to pretty much halt here: C:\Work\git\rayak\examples\sinatra\>igem install --verbose sinatra GET [http://rubygems.org/latest\_specs.4.8.gz](http://rubygems.org/latest_specs.4.8.gz) 302 Moved Temporarily GET [http://production.s3.rubygems.org/latest\_specs.4.8.gz](http://production.s3.rubygems.org/latest_specs.4.8.gz) 200 OK GET [http://rubygems.org/specs.4.8.gz](http://rubygems.org/specs.4.8.gz) 302 Moved Temporarily GET [http://production.s3.rubygems.org/specs.4.8.gz](http://production.s3.rubygems.org/specs.4.8.gz) 200 OK After quite some time, it proceeded and went on with the install as expected. With JRuby 1.6.7 it looks like this. Very similar as with the above, but a _lot_ faster. Is there a significant performance bottleneck with the current IronRuby, or is it caused by some form of timeout or similar?

Hehe, that was a prompt reply. 🙂 Generating the rdoc is taking some time yes, but this was actually before it even managed to start downloading the .gem file. It’s sitting and generating up the rdocs right now as we’re speaking… What is your general perception of IronRuby, performance-wise? Comparable to other platforms or lagging slightly behind?

Try running with the --no-ri and --no-rdoc flags, I suspect generating documentation is what is taking the time. ~Jimmy On Apr 30, 2012, at 4:10 PM, Per L.

Per, I find it quite fast, and the .net integration fascinating.
