It may not have anything to do with Apache - it could just be a bandwidth issue. Try to run apache bench from your web server on itself. For example, here's the command to run apache bench to serve up the /images/rails.png file from the webserver itself. ab -c 1 -n 20 http://127.0.0.1/images/rails.png
That command requests the image 20 times, with 1 concurrent request. You can adjust the numbers for whatever scenario you want to try out. In the output, you can see how fast apache is serving up the file. I just ran this and apache bench gave me: Requests per second: 1766.00 [#/sec] (mean) Now, try it from a remote box. For example, if I now run: ab -c 1 -n 20 http://www.somethingnimble.com/images/rails.png I get: Requests per second: 23.33 [#/sec] (mean) Apache bench will also give you the transfer rate. For my two test runs, the results are: Transfer rate: 3532.01 [Kbytes/sec] received Transfer rate: 46.65 [Kbytes/sec] received So clearly Apache is serving up the images quickly - it's just bandwidth that is slowing it down. MPM worker is supposed to be better for multi-core servers, but if you're noticing sluggish page load times, I don't think it will be your solution. A couple other things: are you using Rails asset hosts? If you serve up your assets from different subdomains, the browser will load more at once. Also, are you using the :cache option of stylesheet_link_tag and javascript_include_tag to combine smaller css and js files into 1 larger file? Are you using gzip to compress your css and js files? Safari has a page load timeline view that should give you good visibility into why your page load times are slow. -Dan Manges http://www.dcmanges.com/blog On Sep 21, 8:01 am, David <[EMAIL PROTECTED]> wrote: > We are running apache 2.2, mongrel and RoR 2.1.1.
