Did you calculate how many req/s is 1 million page views per month? You 
would be surprised how low that figure actually is.

Anyway, unlike twitter you will be able to do page caching on your most 
viewed pages, that means Rails won't be hit and you'll be able to 
achieve high performance.

[Rails] Re: ROR performance for milions pageviews/month

[Tom Lobato]

Hi all!
Thank you very much for the replys, all util information for my
decisions.

As Chris noted:
- My first post need to be fine tuned. Until next monday
I will post the answers for the three questions (actual hardware, app
type 
and access peak/average relation).
- I`m most interested in knowing whether or not a Rails
equivalent to 
current ASP application (and the new app that will be developted) will
be
capable of running
on the same hardware and infrastructure as my 
existing setup with
approximately the same resource requirements and 
performance.

For now, I can make only a little fine tune: I said one milion
pageviews, 
but it is not exact, because 50% of the pageviews are consumed by the 
forum, and the new rails site won`t include the forum, rather we will 
use Vbulletin or Jive SBS. Also, the rest 50% pageviews are consumed
partially
by static content.

Regarding hardware, I already use slicehost for some projects and like
it.
I`am thinking about to use 2GB slice:


  
Plan
RAM
Storage
BW
Monthly Cost
  
   

  2GB slice
  2048MB
  80GB
  800GB
  $130

  

from http://www.slicehost.com/

Of course, it is just a possibility, since this decision depends
strongly of the 
research I`m doing now (including your replys).

ASP application will be capable of running on the same hardware and
infrastructure as your existing setup with approximately the same
resource requirements and performance.  If I were sitting down with you
as a consultant, I would immediately ask the following questions:
  
What does your current hardware and infrastructure solution
look like?  (i.e. number and type of servers, where hosted, etc.)

What does your application look like?  (i.e. mostly static
content, dynamic application functionality, little/lots of Ajax, etc.)
How much higher is your peak load than your average load? 
(i.e. 10x, 50x, 100x, etc.)
  
Without that information, you're going to get a lot of answers about
how Rails scales well without really knowing whether or not Rails will
scale well for you.  However, if we assume a peak load somewhere
between 10x and 20x, you're talking about something on the order of a
few hundred requests per minute which is not such a high demand to
place on a basic Rails app running on a single recent model server,
especially if you're able to implement some form of caching.

What would happen if you put an iFrame on the current site that
requests a response from a rails test app? It could be invisible to
the end user, and the requested asp page wouldn't depend on it. You
would be able to look at the logs and follow the activity from the
rails site. This might give you some basic insights into performance
issues.

[Sazima]

Tom,

Check Joyent's article on LinkedIn scaling (Scale Rails to 1 Billion
Pageviews):

http://www.joyent.com/a/scale-rails-to-1-billion-pageviews

Also, we're currently revamping a couple very large sites using rails,
so we're quite confident on its performance. (vc tá em SP?)

Cheers, Sazima

cardplayer.com and spadeclub.com also run Rails.  There's a ton of  
stuff going on much of which isn't cacheable (at least for  
cardplayer.com).  3 years ago cardplayer did about 8 mil views a day  
for a couple of weeks (during the WSOP).  There's some hardware behind  
it, but we'd have done that with any other platform as well.

also, doesn't penny-arcade run rails?  they do a ton of traffic.

That's a horrible example.  Twitter is notorious for poor performance 
and frequent outages.

However, GitHub and Lighthouse are good examples of high-traffic Rails 
apps with good performance.  So is Backpack, I think.  So it certainly 
is possible.

Rails can scale to support that.  The problems you'll run into after a  
certain point aren't really Rails specific, but will apply to any site  
serving that amount of traffic.

Also keep in mind that 1mil views/month spread out evenly is only .38  
views a second.  Which isn't much.  Of course traffic is never spread  
evenly, but you get my point.

You might want to check out http://railslab.newrelic.com/scaling-rails

Twitter has more than this, therefore its possible.
