...Load Test Correctly. I found that series of posts to be pretty helpful in testing Mongrel/Rails. IIRC, about this was about 10 months ago.

Rails instances themselves are almost always single-threaded, whereas Mongrel, and it''s acceptor, are multithreaded. In a situation with long-running Rails pages this presents a problem for mod_proxy_balancer. If num_processors is greater than 1 ( default: 950 ), then Mongrel will gladly accept incoming requests and queue them if its rails instance is currently busy. So even

Link helper namings counterintuitive in an environment where convention over configuration prevails: <%= link_to_javascript ''myscript'' %> <%= stylesheet_link_tag ''mystyle'' %> A simple def in ActionView::Helpers::AssetTagHelper would fix things in a nice, backward-compatible way, such that: <%= link_to_javascript

Hi, I was wondering if this is normal or if it something i need to wonder about. I get Monit alerts that my mongrels PID files have changed.

Is there any possibility to divide too long text in a plot to two or more lines, when using labels-parameter in the text()-command?

I''ve posted this to rails-deployment as well. I have to administer a medium size rails app (1''5 million requests each day), recently I''ve switched from lighttpd + fcgi to apache + mongrel. In the following lines I am going to describe the platform: All machines are running Debian Etch, with 4 gb ram and dual core intel32 processors. Web server runs debian''s

Is there a good plugin that does per page authentication management? For example, I want to allow users to create pages and share them with specific users, all users, or none at all on a per page basis. Benjamin -- Posted via http://www.ruby-forum.com/.

In May I had problem with mongrels suddenly consuming huge cpu resources for a minute or two and then returning to normal (load average spikes up to 3.8and then back down to a regular 0.2 over the course of 5 minutes, then again 1/2 hour later. or 4 hours later, no predictable rhythm). I posted to Litespeed forums because I thought the problem was there but didn''t get far. And a week

I am looking for a good CMS based on Rails that has at least these attributes: 1. Ease of use ( as it will be used by people who are not html literate) 2. Very easy/flexible to change layout.

Hi, I''ve got an app which will only be dealing with a few requests a minute for most of the time, then will shoot up to a continuous 20 req/s for an hour at a time. We''ll potentially be running a lot of instances of this app on the same server. Is there any way to have additional instances of Mongrel be started when the existing instance(s) stopping being able to handle

...ed made about polling/and inbox strategies, and I think I just can''t work around my feeling that a "wrong" request that takes up too much time should be able to lock subsequent requests in mongrels queue. That''s what I have a balancer for, right? :) So I tried Robert Melas hint[1] and used BalancerMember http://foo max=1 acquire=100 to see if that helps. But I may have hit a bug[2], and this does not work for me. Does this work for someone? With what version of Apache? I am running 2.2.4. Or do all of you have only very fast requests that do not take more than a...

ActionController::Routes.recognize() to obtain a URI for matching. If ActionController::AbstractReqeust:;relative_url_root is non-zero length, then the AbstractRequest::path chops that many characters off the request URI before returning the new URI. The problem is that this chopping happens whether or not the URI begins with the relative URL. I would expect the method to test whether the
