The --enable-pthread might be for compatibility with the tcl/tk package
(IIRC correctly, they should either both use it or both not use it).

I'm not bashing Debian in general, just the Debian approach to Ruby packaging.

In general I'm quite happy with Debian/Ubuntu, but not with deb packaged Ruby.

Shall I bite?

So what's wrong with Debian's Ruby packaging and what would be the proper
way? (AFAIcan see the above problem doesn't have anything to do with
Debian's packaging but instead with a compile flag?)

Probably it depends on architecture of the binary-package which was
prepared for.
it's too "universal". for example binary packages are made por i386 ,
not for i686.

I got 53648 iterations per second running the following program,
on an Intel 3.2 GHz HT, Win XP machine:

It took 18.64 seconds to run. 53648 iterations per second.

start_time = Time.now

for i in 1..n
t = (1..10).inject {|x, y| x + y }
end

finish_time = Time.now

p t

print " #{(n / (finish_time - start_time)).to_i} iterations per

this is on a 3.2Ghz with HT, VISTA, guess vista is slower than XP

Hi,
How fast does your Ruby run?

Ruby 1.8.5 patch 12 on powerpc-darwin8.8.0
It took 38.723017 seconds to run. 25824 iterations per
second.

PowerPC G4, 1.42 GHz ;)

Is that missing a decimal point after the 17?

The performance gain I got from Ruby 1.8.6 to Ruby 1.9 is only from
about 52,000 iterations per second to 58,000... I wonder why other
people get so big performance gain instead. is it because they compile
their only Ruby 1.9.

I downloaded the Ruby 1.9 from

Ruby 1.9.0 Binary (md5: 9809f6e9bc7795f83612b369e36c8724) Developer
version (experimental)

in http://www.ruby-lang.org/en/downloads/

for the Win XP version.

Ruby 1.8.6 patch 0 on i686-darwin8.10.1
It took 9.495808 seconds to run. 105309 iterations persecond.

Ruby 1.8.6 patch 110 on i686-darwin8.10.1

Slightly slower, running on battery but I don't think it makes any difference.

it's too "universal". for example binary packages are made por i386 ,
not for i686.

However the data I have available indicate that compiling ruby for i486
(afaik Debian compiles for i486 and not i386) instead of against i686
doesn't matter much:

Here are the real results, indicating how ruby was compiled:

1. CFLAGS="-O3 -mcpu=i686 -march=i686 -mtune=i686" ./configure
--target=i686-linux

Ruby 1.8.5 on i686-linux
It took 6.561333 seconds to run. 152408 iterations per
second.


2. CFLAGS="-O3 -mcpu=i486 -march=i486 -mtune=i486" ./configure
--target=i486-linux

Ruby 1.8.5 on i486-linux
It took 6.847393 seconds to run. 146040 iterations per
second.

Which would make a difference of rougly 4%.

Am I misstaken?

Anything else that sucks so bad with Debian packaging?

I guess he typed the results instead of copying and pasting, judging
by the missing period after 17 in the first result; so that may be a
typo too.

Anyway, here it goes:

If that is true, then is the release version specifically compiled to be
slow? Which compiler is the best and which settings to use for a "roll
your own" ruby for windows? Unix?

As far as I've been able to determine, with gcc, the compiler settings
should be "-O3 -march=<architecture>", where <architecture> is the chip
name, for example "-O3 -march=athlon64". There doesn't seem to be much
gain from going from O2 to O3, but it's non-zero. The tests I've looked
at indicate that it's the "-march" piece that does the real job.
Incidentally, I saw a post go by somewhere that had "-march= -mcpu=
-mtune=" flags all set. The only one you want is "-march" -- the others
are redundant or ignored or both.

See http://www.jhaampe.org/software/ruby-gcc for the details.

I can't help you with the Microsoft or other Windows compilers. Cygwin
or MSYS/MinGW compiling, on the other hand, should work the same way as
Linux -- you've got gcc, so use "-march=" and "-O3".

Oh, and finally, the latest Ruby from svn...

4. CFLAGS="-O3 -mcpu=i686 -march=i686 -mtune=i686" ./configure
--enable-pthread

What does it look like without --enable-pthread?

Without --enable-pthread, it still gets linked with libpthread.so. And
performs as mentioned.

If I put --disable-pthread, the compile fails, saying "No rule to make
target thread_.h, needed by error.o".

Oh, silly me :) -- YARV uses pthread for its threading now, so of course
it won't work without it.

I wonder if it will build with GNU pth?

Ruby 1.8.2 on universal-darwin8.0
It took 5.920011 seconds to run. 168918 iterations per second.

I changed the scope of x & y and eeked out some more speed.

x, y = nil
for i in 1..n
t = (1..10).inject {|x, y| x + y }
end

--------------------------------------------------
n = 1_000_000

start_time = Time.now

for i in 1..n
t = (1..10).inject {|x, y| x + y }
end

run_time = start_time - Time.now

p t

puts
print "Ruby ", RUBY_VERSION, " patch ", RUBY_PATCHLEVEL, " on ",
RUBY_PLATFORM

puts
print "It took #{runt_time} seconds to run."
print " #{(n / run-time).to_i} iterations per
second.\n"
