Here's something to note when using net/http in Ruby (which open-uri
wraps). Even though it's about as fast as other options, it uses a
huge cpu load when compared to others (on ruby 1.8.6):

Interesting. My main goal was to get a feel for how jruby and the
direct/embedded stuff compared to mri ruby and straight up http. But
obviously, the data and these tests are not realistic at all. Thanks
for
your feedback guys.

I just had a brief conversation with Yonik on this to get his way
more
expert opinion, and it really boils down to this in this particular
test...
the query itself is incredibly fast (1 millisecond or less QTime Solr
reports) since there are no documents. So what these differences are
showing is merely the difference between HTTP and a method call -
with
nothing else (of note) going on.
In a realer world scenario, the HTTP overhead makes less difference
as the
work being done in the query/faceting overshadows the communication
overhead.
There's lies, damned lies, and benchmarks :)

Yeah I overlooked all of that. Thanks Erik. So could a better query
test
be
an incremental one based on id like:
100.times do |id|
q = "id:#{id}"
# query request here...
end
?
Would you happen to know why the solr home and data dir never really
change?
Anytime I use commons http or embedded, a "solr" directory is
created in
the
same directory as my script. Even though I'm setting the home and
data dir
in my code?

You'll want to close that core, otherwise the JVM doesn't exit. I
changed
this to:
@core = ....
container.register(core_name, core, false)
and used @core there.
query = {'qt' => 'standard', 'q'=>'ipod', 'facet.field' => 'cat'}
Note that faceting is not enabled unless there is also a &facet=on
params = hash_to_params(query)
max = 1000
Benchmark.bm do |x|
x.report 'http commons' do
max.times do
http_commons.query(params)
end
end
x.report 'embedded' do
max.times do
embedded(solr_home).query(params)
end
end
end
And I added an:
@core.close
at the end.
