Subject: Help interpreting benchmark results

I ran this simple benchmark:

Benchmark.bm do |x|
  x.report('Curl::Easy.http_get') do
    Curl::Easy.http_get(text)
  end

  x.report('RestClient.get') do
    RestClient.get(text)
  end
end

RestClient uses the standard Net:HTTP library so the benchmark is really
trying to compare Net::HTTP vs curb (libcurl bindings).

These are the results I get:

                                  user     system      total        real
Curl::Easy.http_get   0.070000   0.130000   0.200000 ( 26.319104)
RestClient.get          0.970000   0.580000   1.550000 ( 23.557923)

I get these results consistently where curb's user, system and total
times are dramatically lower than Net::HTTP's. However, Net:HTTP is
reported to run faster by the real column. Shouldn't the reported real
time be consistent with the other columns?

I'm running this benchmark on a 2.4Ghz Core 2 Duo with  2GB RAM MacBook
Pro, if that helps.

Thanks,
Juan
