Hi Everybody, my rails 1.2.5 application runs in a linux embedded environment with serious memory constraints. I would need to know how small a memory footprint I can hope to get. I run ligthtpd with only one dispatch and I did already remove actionmailer and actionwebservice which I do not need. Currently top shows a memory footprint of 720K for lighttpd and 25M for the dispatch.fcgi process. The smallest the footprint, the better so any suggestion on how to reduce it is very well accepted. Thank you in advance, Emanuele. ---

That’s about as small as you can get. I love Rails, but it is a memory hog and it’s only going to grow as you implement more features / serve more users.

IIRC the unicode tables are quite big, and if you don’t need the multibyte love you can probably lose them. Fred ---

Have you tested this with 2.0? I assume the footprint will be much smaller with a lot of functionality moving to plugins. -Bill removed\_email\_address@domain.invalid wrote: > Thank you in advance, > Emanuele. > > > – Sincerely, William P. ---

I’m not too eager to delve in the implementation of a not already stable version of rails… however has anyone tested it? Where can I find a list of the features moving to plugins? Emanuele. ---

As far as finding features moving to plugins, just keep an eye on your log file as you will get a deprecation warning for anything. 2.0 has been really stable for a while now and RC2 was released today which is hoped to be the final release before 2.0 (which may just bee a week or 2 away)! > **[Rails 2.0: Release Candidate 2](https://rubyonrails.org/2007/11/29/rails-2-0-release-candidate-2)** > > After another batch of fixes, tweaks, and buckets of polish, we’ve prepared the hopefully last step before 2.0 can go final: Release Candidate 2. If nothing major pops up, expect the final version to land within the next week or two at the most.As... -Bill Emanuele R. wrote: > > > Emanuele. > > > version of rails… however has anyone tested it?
