I have a Wordpress which currently takes about 1.8s to 2.5s for the home page to completely load in my country. The page weight is about 700Ko (static content included).

In order to increase performances, I'm considering two solutions:

1. Switching to a dedicated host.
2. Using amazon s3 cloudfront to serve static contents.

My current shared hosting have servers in a neighboring country but not exactly in mine, and both amazon and the dedicated hosting have some, so that's already an advantage. So considering all that, I still have three questions remaining:

• Currently having a low traffic (100 unique visitors/days, but growing) will it make a huge difference between my shared hosting and a dedicated server ?

• Knowing that I already use a cookie-less domain to deliver static contents (but using a redirection to the same server), would using amazon s3 make a real difference ?

• Talking about the cons of dedicated vs amazon s3, if I choose for the dedicated server something like Ubuntu server and do daily package updates and have only port 80 open, would it be sufficient in terms of security (in comparison with my current shared hosting which manage everything for me) ?
