Hi List, I''m currently investigating some possibilities for deplyong my Rails app. I developed it on Windows XP, but I thought I should give linux a run too. I expected some performance benefit, but not of this level. See the table for the measurments, all taken from the log by clicking 5 times on the same method. PC = old pc, Athlon xp 1800, 512 MB, 7200 rmp HD, Win XP Laptop-WinXP = Intel Centrino 1.5Ghz, 512MB, 4200 rmp HD, Win XP Laptop-Ubuntu = same laptop, but now with Ubuntu 7.04 Beta All tests were run in development mode, with webrick 1.3.1, mysql configured just the same: PC-WINXP LAPTOP-WINXP LAPTOP-UBUNTU (first test) 0,27 0,5 0,12 0,24 0,49 0,09 0,95 0,26 0,09 0,25 0,68 0,88 1,14 0,28 0,2 (second test) 0,72 0,43 0,29 0,61 0,43 0,14 1,28 0,25 0,25 0,41 0,57 0,25 0,83 0,3 0,13 Can anyone explain me why Rails or Ruby is that much faster on ubuntu? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Re: Why is Ruby on Linux so much faster than on Windows?
Some people claim that linux is faster than windows, i don''t have technical base to say that, maybe even those who claim that. Also, linux doesn''t need graphical interface, and grafical interfaces consume CPU cycles too, Linus and UNIX where created to have simple design. here is a text talking about Linux vs. Windows performance. http://blogs.ittoolbox.com/linux/locutus/archives/why-linux-still-runs-faster-than-windows-14828 you can find more with google On Mar 31, 7:57 am, "Joram" <joram.bar...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> Hi List, > > I''m currently investigating some possibilities for deplyong my Rails > app. > I developed it on Windows XP, but I thought I should give linux a run > too. > I expected some performance benefit, but not of this level. > > See the table for the measurments, all taken from the log by clicking > 5 times on the same method. > > PC = old pc, Athlon xp 1800, 512 MB, 7200 rmp HD, Win XP > Laptop-WinXP = Intel Centrino 1.5Ghz, 512MB, 4200 rmp HD, Win XP > Laptop-Ubuntu = same laptop, but now with Ubuntu 7.04 Beta > > All tests were run in development mode, with webrick 1.3.1, mysql > configured just the same: > > PC-WINXP LAPTOP-WINXP LAPTOP-UBUNTU > (first test) > 0,27 0,5 0,12 > 0,24 0,49 0,09 > 0,95 0,26 0,09 > 0,25 0,68 0,88 > 1,14 0,28 0,2 > > (second test) > 0,72 0,43 0,29 > 0,61 0,43 0,14 > 1,28 0,25 0,25 > 0,41 0,57 0,25 > 0,83 0,3 0,13 > > Can anyone explain me why Rails or Ruby is that much faster on ubuntu?--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Re: Why is Ruby on Linux so much faster than on Windows?
Were they both fresh installs of the operating system? If not that could easily explain it. Because I WinXP primarily it has tons of ''junk'' on it. I try to keep my linux stuff as clean as possible (though I''m not very good at it because I''m still learning linux). I''m pretty sure that most linux distros are pretty lean after the initial installation, even Ubuntu. At least they are compared to Windows. I guess that could explain it too.

Re: Why is Ruby on Linux so much faster than on Windows?
Ruby in general isn''t any noticeable slower on Windows than it is on Linux, but Windows in general is much slower in file operations, and so it is with Ruby. A Rails application uses many files, and hence the slowdown.

If I get a flash memory USB stick and mount it (WinXP _or_ Linux), will it read and write files faster than those little spinning platters inside a hard drive? It seems there are those who put their entire project, Apache, Ruby, Rails, SVN and everything onto those things... -- Phlip http://flea.sourceforge.net/PiglegToo_1.html --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Separate from these physical characteristics you also need to figure in the overhead from the USB port that usually is fairly CPU costly. So it depends. Rails performs a lot of smallish reads but also does a fair amount of log writes. In all I''d still prefer the hard drive performance-wise, but I don''t have the numbers to back it up.
