Nope, it's running in the production environment.

Hi, are these results in production or development?
There is no difference between the two in this case, so the script
doesn't set RAILS_ENV at all.
Talking about template rendering, I'm just wondering if anyone has
thought of pre-processing the template for a production environment.
For example, I'd imagine it's might convenient to do things like '<%
tylesheet_tag %>' etc when linking in files. But, each time Rails hits
one of those, it needs to render it. Would it make sense to have a
smart pre-processor that goes through the templates to see what
constants there are (like links to the same stylesheet, javascript
files, etc.) and even things like "form_start_tag"/ "form_end_tag" etc.
to pre-render it so that the number of times you need to create
something is reduced.
Yes! See Stefan Kaes' template optimizer: http://railsexpress.de/plugins/trac
Has anyone benchmarked the time for rendering a page with many or few
such items?
Yes. See Stefan's blog; he regularly benchmarks his apps against each
new Rails release. I think he's covered the impact of the template
optimizer.

I would think someone in the "core Rails team" would step up to the plate for Rails-specific benchmarks. But if the specific case under discussion here -- ActiveRecord -- turns out to have a bottleneck somewhere in the Ruby interpreter, rather than just an inefficient strategy in the ActiveRecord code itself, then I'd say this benchmark belongs in a Ruby benchmark suite rather than a Rails benchmark suite.

No, sorry: it doesn’t load a Rails environment at all, just vanilla
Active Record.
The Rails environment has no bearing on Active Record in isolation,
beyond choosing the default database connection:
$ grep -r RAILS_ENV lib/ |grep -v svn|wc -l

Your Rails app reloads application classes during development so some
AR caches, like the per-class table metadata, are wiped as a result.

Yes, I'd like to see this discussion continue on the Ruby list, because there are some things to be learned from experiences with ActiveRecord. So, some questions for Brian:
1. What's your platform, and what version of Ruby are you running?
2. Is it possible for you to abstract a subset of your application as a benchmark, suitable for profiling?
3. Is it "simple enough" that it will "probably work" with the recent jRuby implementation of Rails?

Mohit, do you mind if I ask how you're posting messages to comp.lang.ruby? While reading Jeremy's posts I realized I didn't see either of your posts via my newsreader. When I noticed the first time, I thought my ISP might have just randomly dropped some posts, but when I went to:
I saw both of your posts, but neither showed up via my newsreader (Thunderbird). That seemed too coincidental for a Bellsouth screw up, so I thought I'd ask.
Thanks,
Brian

Well, the "application" in this case is just a simple test for benchmarking 
See my previous post for the Rails controller code (what little there is of it).

I would hope so - it doesn't get much simpler.

$ ruby -v
ruby 1.8.4 (2005-12-24) [i486-linux]
A couple of suggestions here:
1. Download the latest Ruby source -- 1.8.6 pre something.
2. Compile it for your architecture -- set CFLAGS = "-O2 -march=xxx"
where "xxx" is your architecture -- it's an AMD64 of some kind, right?
If you're running a 64-bit system, make sure you have a recent 64-bit kernel and GCC 4.1 -- older compilers suck wet dog fur on the 64 bit machines.
That should get you somewhere in the 10 - 30 percent speed improvement over a 486-compiled Ruby 1.8.4. It might be more, but just doing the 1.8.6 and the -O2 / march= stuff is pretty much mandatory.
$ uname -a
Linux airstream 2.6.17-11-generic #2 SMP Thu Feb 1 19:52:28 UTC 2007 i686 GNU/Linux
That should be OK -- most likely it's user time anyhow, not kernel time.
$ rails -v
Rails 1.2.1I'm running Ubuntu 6.10
That should be fine too. The compiler is probably more important.
2. Is it possible for you to abstract a subset of your application as a benchmark, suitable for profiling?

Yeah, I saw that.
3. Is it "simple enough" that it will "probably work" with the recent jRuby implementation of Rails?
I would hope so - it doesn't get much simpler.
I know Charles Oliver Nutter reads this list -- he's looking for tests for the latest jRuby/Rails.

Interesting. I guess I mistakenly assumed a one-to-one correspondence between comp.lang.ruby and the "ruby" forum at http://www.ruby-forum.com/ but now that I look more closely at the latter, it does say "Gateway to the ruby-talk mailing list."
Thanks for confusing me Jeremy

I'm running a 32 bit kernel because 64 bit was, let's say, problematic. My gcc is 4.1.2.
I don't believe ruby-forum is involved here. I think Jeremy cross-posted from the Rails list.

Preview 3 is out:
ftp://ftp.ruby-lang.org/pub/ruby/1.8/ruby-1.8.6-preview3.tar.gz
I used it for the earlier benches and it has posed no problems for any
of my Rails apps in development.
Be sure to work with Rails' 1-2-stable branch (or edge) for a
smattering of 1.8.6 compatibility fixes due out in the upcoming Rails
1.2.3.
