Page cached performance

Rails

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
