Hello all, I’ve recently started a project and I wanted to give ruby 1.9 + rails a chance. Well everything works great, so far haven’t encountered any gem that didn’t work (so anyone out there you should give it a try). There’s only one minor glitch: on ruby 1.8.7 loading rails environment takes 1-2 secs, on 1.9.1 it takes ~10 secs. Maybe anyone had similar problem? I’m on ubuntu 9.10 and I compiled ruby from source (as I’ve noticed it works ~20% faster than apt version). ---

I’m having similar issues. I’ve tried on a Windows box, as well as Ubuntu 9.04 and 9.10 (both of which were VirtualBox with Windows XP as the host, but I tossed all the RAM I could at them). All three environments have rails 3 loading at an unacceptable speed (30-60 seconds before the environment is even loaded). I’m at my wits end on this - although I did not try anything other than 1.9.1 for this. I’ll go build 1.8.7 from source on one of the ubuntu images and give it a shot. ---

Have you tried ruby 1.9.2-dev? ---

Rails 3.0.0.beta And as far as loading rails, I mean anything involving the ‘rails’ command. rails console, rails server, rails generate - all 30+ seconds. Anything involve the rake tasks rails ships with: rake db:migrate, rake test:units - 30+ seconds. I honestly haven’t even gotten into actually running the server yet - I’ve been writing models and test units, but I did test on just webrick and response time - 30+ seconds. This is on Windows XP, Ubuntu 9.10 or Ubuntu 9.04 (both ubuntu were on VirtualBox with XP as the host). I’ve tried Ruby 1.9.1 and 1.8.7. 1.8.7 just made things vastly worse - 2+ minutes to start some things. ---

Windows 7 Ultimate can get things loaded in less than 20 seconds. BTW, I have the following system configuration: Mac Pro: Mac OS 10.6.2 8-core 2.93 GHz 32 GB RAM VMWare Fusion 3 - Windows 7 Ultimate (64 bit) and Ubuntu 9.10 (64 bit) Also, I have scaled things all the way down using 1 and 2 cores and I was able to get the same results. Again, Rails 3 is currently in Beta. Thus, all the needed optimizations are not in place and I’m quite sure that there’s a level of debugging logic within the code base. This debugging logic will most likely be removed and optimizations will be put into place for the first release candidate (RC). Good luck, -Conrad
