Hello,

I added caching for my welcome-page, and i get 31reqs/sec. Is it good  
enough? How i can speedup page loading?

Thanks

This is a rather imprecise question: good enough for what? If you are  
running in development mode, you’ll probably get different numbers  
when you run in production mode (and quite probably running more than  
one mongrel)

If you’re getting output like this it means that page isn’t being  
loaded from the cache.

Page caching works by generating an HTML file from your output so  
future requests won’t touch rails and will be handled entirely at the  
web server level. By default, caching isn’t active in development  
mode so you won’t see any effect from it unless switching to  
production mode.

Once you have page caching working, improving performance works just  
the same as for any HTML page: reduce the number of images,  
javascript files, css files, etc, tune up your server, and things  
like that.

Thanks for reply

Please check is am i right doing caching?

When i use caches\_page i got a html file, for example welcome.html.  
Now i’m trying to cache my partials this way:

\<% cache "lang" do %\> \<%= render :partial =\> '/langbar' %\> \<% end %\> \<% cache "tologin" do %\> \<%= render :partial =\> '/tologin' %\> \<% end %\> \<% cache "header" do %\> \<%= render :partial =\> '/header' %\> \<% end %\>

After this in folder tmp/cache i got a lang,tologin,header.CACHE files  
and i get 62 reqs/sec and for some pages - 10000 reqs/ses.

This is my log
