#script tags are blocking operations, it cant do anything until it gets the script back; 
#Remember it has to request all of the script links individually from the server; 

#On heroku it will only include one script file and one css file which will be much faster as doesnt have to make lots of request to the server; 

#It is hard to debug stuff on heroku; 
#You can ask rails to run the production environment locally; 

rails server -e production #If you are having a problem that only appears in production, you can make the production environment run locally; 

#If you want to run production locally you have to run a rake task locally 
RAILS_ENV-production rake assets:precompile #It will compress javascript and css into a single file; 
config/environments/production.rb serve_static_assets = true

rails server -p 3001 #You can run multiple rails servers at once if you specify a new port;

Have a look in the pageSpeed tab #Have a look at the googleIO video; 
#How to get rails to minify your html; 

#Google take response time into account when they are ranking things; 

#Use cdn as the user likely to already have it cached; 
#As long as your scripts are making requests to different servers you can make requests in parrallel, good idea to use a CDN; 
#Chrome can now make up to 4 reauest on the same machine at the same time; 

#The disadvantage of CDNS is that you are dependent on the CDN, if the server goes down you are FUCKED!

#Have the CSS at the top, all the CSS will be loaded at the top thus you will see stuff with styling; 
#Your javascipt should be at the bottom of the page after the page has been loaded; 
#Move your javascript so it is just before the closing body tag;
#Modernizer needs to be at the top of the page; Modernizer makes old browsers behave like new browsers; 

#Evertime you use a different domain name it needs a IP address to look up that name, thus avoid using too many different domain names;
