I have optimized my website and apply many advices found on the Google search. but finally i have about 400~600ms of time to first byte. Does it normal or I can lower it?

For dynamic data it it about 500~600ms base on the code that creates the content.

I think it must be lower for static files but for static files it hit the 400ms of time to first byte. why?

Using Apache2.2 on Ubuntu 12.04 VPS

thanks.

Yes. If in doubt, try checking the time to first byte of popular websites in your market, or take a look at this article : https://moz.com/blog/improving-search-rank-by-optimizing-your-time-to-first-byte

If your ttfb is between 400-600ms, you have nothing to worry about on that score.

Although you may possibly be able to shave off a few ms, if you are doing this because you have one website and want it to be fast for users and perform well in search engines, then there are almost certainly other more useful areas you could be working on.

A TTFB between 400 - 600 ms may be normal for non-optimized servers / code, but it certainly is not the best you can get. You can optimize your server with Nginx, Varnish, HHVM or Redis (or multiple) to make both static content and dynamic content load faster.

But don't look only at the TTFB, there are other numbers that matter.
