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

Design flaw? - num_processors, accept/close
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

instance variables in layouts
There''s probably a simple answer to this simple problem, but I am trying to figure out how to reference an instance variable within a layout. In the controller, one method corresponds to a view of the same name. Those instance variables in the method can be used in the corresponding view. However, I want my instance variable to be accessible throughout all my views, not just one,

User/Password Management: Mapping items to inidividual users
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/.

random cpu spikes, EBADF errors
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

Automatic Scaling
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

Bug in AbstractRequest.path() ?
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

Battle of Namings: stylesheet_link_tag vs link_to_javascript
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
