Aslak,
The best time I get is 6.3 seconds. I'm using "time script/server"
command and hitting Ctrl-C immediately after I see "** Use CTRL-C to
stop."
Ok, so you have 5 seconds of additional overhead. I'm guessing that
RSpec takes maybe 0.5-1 seconds of the remaining 6 seconds overhead,
and that plugins, gems and other code the rest. Maybe you'll find
out more with http://ruby-prof.rubyforge.org/

Worth mentioning that I went down a huge rabbit hole with a similar
problem (slow load of rails environment) a few weeks ago, and it
turned out that all I needed was a reboot. (Mac OSX Leopard). Boy, did
I feel like a chump!

Greetings,
I found out that running RSpec on Rails takes too much overhead. It
takes more than 16s per run although the specs only take less than
6s, like seen below. That means almost 11s overhead.
I can't find the bottleneck. I use latest rspec, and rails 2.2 on
Debian.
$ time rake spec
(in /home/reza/system)
....................................................................................................................................................................................................................................................................................................................................................
Finished in 5.493595 seconds
340 examples, 0 failures
real 0m16.497s
user 0m14.059s
sys 0m2.266s
I know that Debian's ruby is slow. So I tried using enterprise ruby.
Not much difference
$ time /opt/ruby-enterprise/bin/ruby /var/lib/gems/1.8/bin/rake spec
(in /home/reza/system)
....................................................................................................................................................................................................................................................................................................................................................
Finished in 3.170093 seconds
340 examples, 0 failures
real 0m12.033s
user 0m9.948s
sys 0m1.735s
The overhead is also felt when using autospec. Even using sqlite's
in-memory-db doesn't change much.
Can anyone give me hint about what happens and what to do to
overcome it?
How long does ruby script/server take before the server is up?
Aslak
Thanks all.
