I''m running Windows XP Pro on a not-so-new machine, Pentium 4 2.4GHz with 512 RAM. I''ve got Apache 2 installed and I''m using FastCGI to run Typo in development mode while I design a theme for it. But it''s slow, very slow. Inconsistently slow. If I reload a page, sometimes it happens pretty quickly. Sometimes it takes more than a minute. Sometimes it gives me an error message where the app doesn''t load at all. Sometiems I get the page but without any CSS applied to it (even though reloading it works fine.) I had to firstly limit the number of running ruby.exe processes. Before I configured it to use a maximum of 1, whenever I tried to run Typo a seemingly endless number of ruby.exe would start; so many that eventually my computer would crash unless I quickly ran into Task Manager and shut every instance down. Despite the number of ruby.exe processes that were running, Typo was still slow. Ruby.exe itself takes up 25-40MB of RAM at any given moment which I find to be massive. I''m using the Typo trunk as it''s the only version that works with 1.1. What is going on here? Surely I don''t want my hosting to be like this, slow and RAM-devouring. A PHP blog script certainly doesn''t use this many resources, does it? -- Posted via http://www.ruby-forum.com/.

Even with no applications running it will commit 600MB or more. With MySQL, Apache, Ruby, Rails etc it will commit around 800MB. 25MB per ruby server is about. I''d recomend no less than 1GB of ram on Windows, but 512MB could provide you with gobs of extra memory in Linux ;) Beyond that... Configure Apache to run with a small number (maybe 2?) of static fastcgi servers instead of running them dynamically. It''s most likely the dynamic servers having to startup that you are noticing. When it takes to long Apache can time out. -- Posted via http://www.ruby-forum.com/.
First of all, are you clear on why you''re using Apache+FCGI for development? WEBrick should be fine unless you''re in the tiny minority writing code that needs Apache specifically (e.g. crazy stunt programming somehow mixing PHP or mod_perl and Rails, or testing some convoluted single-sign-on shared with other non-Rails apps on the same Apache). If this is not the case, lightpd is going to have much less overhead than Apache if you''re adamant about running FCGI on your development box (why?!), but WEBrick really is all you need and you''ll drop RAM utilization enormously. Assuming you need to develop against Apache for the reasons above, 512MB is going to be borderline but might be doable. The problem you seem to be having is FastCGI spawining too many processes. If you''re seeing more than three or four at a time, that''s your problem. You should be configured to spawn one, maybe two. Can we see the blocks of your Apache config related to FCGI and your Rails app? The entire FastCGI config block and the VirtualHost block or .htaccess should do it.

I noticed this too but it''s completely resolved if you can get into production mode. The other option seems to be running it without sIFR to render the fonts until you''re ready for production mode. Works very well for me on my mac mini and on our managed server. In dev mode even the 2 cpu server with 2GB ram was using 100% cpu (on one of the cpus). In production it''s perfectly quiet. -Chuck On 4/19/06, Steve Koppelman <hatlessnyc@yahoo.com> wrote:> First of all, are you clear on why you''re using Apache+FCGI for > development?

This computer and even earlier computers shipped with the OS; I find it illogical that it''s "not enough". On the contrary it''s been adequate for a few years now but certainly needs to be replaced. Actually the only reason why I installed Apache/FastCGI is for figuring out how to properly set it up. You see my friend has a shared server and is hosting me but isn''t totally adept on how to run his server besides handing out an account with cpanel. He has yet to figure out how to give me superuser privileges so I can install software for myself (even I don''t know how to do this), so I frequently have to walk him through the installation and configuration of things for Rails. Most recently he installed ruby and rails on the server but I realized I had to use Webrick which seemed inadequate for an actual site. My installation of Apache/FastCGI was merely to become familiar with it. Had I known that it could use so many resources I would have never tried to stick with it. I do find it more convenient than keeping a command prompt window open. -- Posted via http://www.ruby-forum.com/.

The fact that it shipped with 512 doesn''t mean anything. Even with nothing running XP will commit 600+ MB. This means that you run the risk of a page swaps at any time. It will run, it doesn''t run well. -- Posted via http://www.ruby-forum.com/.
