A good server setup can make a huge difference for website performance and may even enhance the ratings in the search engine results since page speed has become an issue.
Http request info
| 'HTTP response code | 200 |
| Download time | 0,13952 seconds |
| Filesize | 7928 bytes |
Server headers
Server headers are the response the server sends before the actual content. A correct server setup can speed up a site and free up server resources. Make sure that all headers are set correct. For example dont cache dynamic content and dont close connections unless there is a good reason.
| HTTP/1.1 200 OK | |
| Date: Fri, 25 May 2012 13:11:34 GMT | The Date header represents the time when the message was generated, regardless of caching that happened since. It is used by caches as input to expiration calculations, and to detect clock drift. |
| Server: Apache/2.2.16 (Debian) | The Server header contains information about the software used by the origin server to handle the request. The server used here is Apache/2.2.16 (Debian) |
| Last-Modified: Sun, 01 Apr 2012 15:25:57 GMT | The Last-Modified header indicates the time that the origin server believes the representation was last modified. The value is Sun, 01 Apr 2012 15:25:57 GMT |
| ETag: "1022c53-1ef8-4bc9fb0baf109" | An ETag is an opaque identifier assigned by a web server to a specific version of a resource found at a URL. If the resource content at that URL ever changes, a new and different ETag is assigned. Used in this manner ETags are similar to fingerprints, and they can be quickly compared to determine if two versions of a resource are the same or are different. "1022c53-1ef8-4bc9fb0baf109" |
| Accept-Ranges: bytes | |
| Content-Length: 7928 | The Content-Length header indicates the size of the body, in number of bytes. In responses to the HEAD method, it indicates the size of the body that would have been sent had the request been a GET. If Content-Length is incorrect, persistent connections will not work, and caches may not store the response (since they can't be sure if they have the whole response). The content length is 7928 bytes |
| Content-Type: text/html | The Content-Type entity-header field indicates the media type of the entity-body sent to the recipient or, in the case of the HEAD method, the media type that would have been sent had the request been a GET. . The value is text/html |
Server location
Server location is important because a server that is located near the customer will serve pages faster then a server located far away
