The company I work for is launching a new web site tomorrow. News of our launch will be published in major publications throughout the week so I want to make sure we are prepared for the load. Production Environment: HP Proliant server w/ 8GB RAM and dual AMD64 Opterons Memcache is used as the session and fragment store (512MB for it) MySQL is running on a seperate server in the same rack We use

What''s a rule of thumb for guesstimating how many Mongrels to use in a cluster for an app? I have an app that gets about 5000 unique visitors per day. I figured I''d give it plenty of Mongrels -- twenty to be specific. After running out of memory and hitting the swap periodically, I scaled it back to five and it still seems to serve up visitors fine. So, is there some super-secret

Hey all, First off, thanks to Rick Olson and whoever else was involved with this plugin... It''s been amazingly easy to implement. I''ve got a question about the path_info parameter, though... It seems that unless the request PATH_INFO exactly matches the path_info passed in to the plugin at inclusion, it won''t actually trigger Add and add the upload to the list of

Most of my machines have apache+mongrel running but the mongrels are using the localhost. In my production environment, I have 4 boxes. I have setup 2 http servers ( apache 2.2.4 ) and 2 app servers. They are currently using lighttpd+fastcgi. Which I am changing this week. I want to get advice from you guys before I actually do this since this is my production env. I have installed apache on the

Hi - I''ve got a pretty popular Rails app on a Mongrel cluster with Apache and mod_proxy_balancer. How do I decide how many Mongrel servers to put in the cluster? I don''t have stats for the number of requests hitting the server yet, but I should have that data soon. The server has 2GB of RAM and has to do a lot of work with RMagick, including generating and storing lots of

Hi all, Starting out with load testing for one of my rails apps and am pretty confused about what the ''best'' way to do this is. I read the tuning article at http://mongrel.rubyforge.org/docs/how_many_mongrels.html but am getting some weird numbers from the tests recommended at the bottom: httperf --server www.theserver.com --port 80 --uri /tested --num-conns <10 second count> httperf --server www.theserver.com --port 80 --uri /tested --num-conns <10 second count> --rate <reported req/sec...

...''ve been following the new mongrel tuneup guide (a huge thanks for that btw) and here are my results. I''ve basically only gotten to the point where I''m tuning up 1 mongrel because I suspect I have a performance problem with my rails app. http://mongrel.rubyforge.org/docs/how_many_mongrels.html The first number is the 10s nconns and the second is the max req/s as per the guide: Lighttpd serving static files: 6000 1800 1 Mongrel serving static files: 2800 200 1 Mongrel serving a bare /login page (without db query, no layout, just an action): 750 50 1 Mongrel serving my full /index pa...

Lets say you have a site that is serving, oh, around 100k unique visitors a day (plain ole'' browser requests) - plus probably ~ 40k uniques to feeds. Assume this site is 90% read like most of the web, so the traffic looks like your typical news or portal site. There are two web boxes behind a hardware load balancer, each doing apache 2.2.3 -> mongrel_proxy_balancer -> mongrel

I''m trying to do some initial benchmarking of our setup, mainly just to establish baselines. I''m essentially using the process Zed outlines in a previous message: http://rubyforge.org/pipermail/mongrel-users/2006-May/000200.html What I''m running into is that Mongrel appears only half as fast as Apache when serving a small static HTML file. If I then add in Apache with
