From: Peter Pallock Date: 2002-10-23T22:42:42+09:00 Subject: Re: ERuby speed issues The below code is being run on an Apache webserver with ModRuby 0.97. (I have also tried running it straight CGI, versus ModRuby.) Despite the numbers from the Ruby profiler (which are below the code), this particular page loads in no less than 8 seconds and up to 1 minute. This is when I go to the page the first time, not even when I submit the form. <% require 'cgi' require 'digest/md5' require 'iblp/iblp_login/loginsession.rb' include LoginManager session = LoginSession.new cgi = CGI.new if session.valid_session? then # This checks a cookie value error_message = "You are now logged in." logged_in = true else error_message = "Please log in below." if ENV.include?("HTTPS") then if ENV["REQUEST_METHOD"] == "POST" then require "iblp/iblp_login/entity/login" login_broker = Entity::LoginBroker.new(Storage::ConnectionBroker.new) login = login_broker.fetch_login(cgi.params["username"].to_s, cgi.params["password"].to_s) if login.trusted? if session.new_session(login.entity_id) then if cgi.cookies.include?("referer") then cgi.header("Location" => cgi.cookies["referer"].value.to_s) end logged_in = true error_message = "You are now logged in." else error_message = "Session could not be created." end else error_message = "Invalid username or password. Please try again." end end else session.set_secure("https://bob.iblp.net") # This does a CGI header redirect end end %> Login <% ERuby.import "include/header.rhtml" %>

That seems a little excessive for a simple page; I ran eRuby for well over a year w/out any similar problems (I currently recoding in amrita). Can you post some example code with timing? ~ Bruce
