I just did an analysis on tools.pingdom.com, results here: http://tools.pingdom.com/fpt/#!/Hyu8qrcXJ/n1bar.com
From this, I gather (the yellow bar) that 1.5 seconds are spent for the user to wait for the server to send the starting data. You also have 128 requested objects, which is ridiculous. The next thing I see is a large number of decent-sized blue bars, which indicates the server is actively sending data to the user.
Looking at the actual data, it seems most of these requests are for
/plugins/* which indicates you have a large number of plugins enabled. Try disabling those that you don't need.
Next, if you still have issues with speed after completing the changes from above, I recommend you look into a CDN system, which is optimized for sending content to locations through accelerated tunnels. This includes switching web hosts.
You may also benefit very much from server-side caching of static resources like images and stylesheets.
http://www.cloudflare.com is a CDN and caching service and may help, and it's free. You don't need to get a new web host if you use this.
If you still have any issues, don't hesitate to update your post or comment below.
