SiteSpeedLab Overall Website Rating for this website
Based on our speed test results table and considering features of the current webserver location (United states, San francisco), we concluded
overall This website speed rank is 9. That means 9% of the sites from the San francisco are slower for visitors than this website.

It is important to understand that you can't evaluate website speed without considering website audience location. You should evaluate the speed of the site considering location of your primary audience (visitors), and not just from abstract tests from various points of the planet. There is a chance that your website is quite slow for visitors from German but pretty quick for Australian users at the same time. Based on a primary audience location data Site Speed Laboratory maintains objective rating. Test servers located in the Germany and Usa are more useful and important to Wikibooks.org because the shares of each country are 18.80 and 13.10 percent respectively.

You should not overestimate the importance of the website speed factor. Google has more than 200 ranking factors and website speed is just one of them.

Website Latency (Ping Test)

Latency Tests

Check details on Ping Graph

Latency affects on the rate of exchange of network packets between the client (user's computer) and the webserver. The lower latency to webserver means the faster start of the processing of all requests to the webserver, and after all the faster page loading. According to our data the average latency to the web server is 80 ms (see details). Test was conducted from 5 different locations. Average latency rating of the website is good (79% websites are slower). For detailed latency stats from different locations, as well as time slices for a month, 3 months and 6 months and more visit Ping Test Graph. We also recommend to take a look at latency rating at the United states, San francisco location. This will give you an idea about average latency values in the region. And the answer to the question of how good this result for the this website.

How to read the graph's data

This graph represents a detailed statistics of website latency. Periodical measurements give a complete picture of website availability from the different areas of the planet. Particular attention is given to the expansion of our testing servers around the world, in order to test the site availability and latency in those locations where most of your visitors are. Of course, the faster access to the site means users get content faster. It means less bounce (bounce rate) and faster ads delivering (and therefore better performance CTR, eCPM). This is even more important given the fact that we've detected Google Adsense ad network code on this site. Ultimately, the best availability of the site gives you an edge over your competitors. More information can be read on our page about the importance of the latency speed for the website speed up.

Why the low latency is important with this site as an example

To display this website browser needs to download 16 objects. Though modern browsers use parallel connection now, we'll simplify the conditions and calculate the time spent by the browser for these sites in a single-threaded mode. Time required to establish HTTP connection only:
3 * website latency * website objects
+ preparation of the webserver response. Number 3 in the formula is a three phase of a TCP connection: sending a SYN request from the client to the server, sending ASK + SYN from the server to the client and the ASK sending from the client to the server. Though we can not calculate the time for a webserver response, the total time for sending and receiving requests for each of the object will be:
3 * 80 ms * 16 objects = 0 sec
Of course, modern browsers use several simultaneous connections to download content from a domain (from 2 to 8 at the time of writing this document). And in some browsers the number of connections can be set manually (Opera). But, if you impose these data on the first site Quantserve.com from the latency table for the city San francisco, it turns out that the difference in time only for the sending and receiving requests to the web server could be: 1.92 sec. Sure, making such calculations must always take into account the audience site, and always make an accent on the fact that the server should always be so geographically closer to the primary audience as it possible. Also we recommend to pay attention to an article about importance of the latency on our site.

DNS Lookup Speed

Browser should lookup domain name and get IP address of the server (208.80.152.2) before downloading the page. We test DNS resolve for this domain from 5 locations. That's how we've got the average time of receiving IP: 0.07s (which is better than 94% of all sites). For more detailed stats look at DNS tests graph and DNS resolve page for United states, San francisco location (Average value on the widget is an average DNS resolve time for websites hosted at the same location).

Page Speed Test

Content-Type's Weights
 
 
Content-Type's Weights by Hosts
 
 
Downloading page itself is the final stage of the testing. Actually, this is the last stage, after which page is displayed completely for user. The download speed depends on many factors. Main factors are the following: the width of the bandwidth up to the domain, the number of simultaneous download threads, speed of the server, a distance between user and domain web server. Recent measurements have shown the speed of page download for this domain is 25.985Kb/s (which is better than 9% of all sites in this region). For more detailed stats check out report for San francisco hosted websites.

 
 
 

Page Speed

Page Speed is a key factor in the website speed estimations (along with DNS lookup speed and website latency). Speed of the page loading, sophisticated subdomains usage for static content (images, css), optimized code (html, js), hosting on fast servers with good latency to its audience leads to good results and, ultimately, to a good website profitability.

While conducting tests we emulate a visit your website using the browser Firefox 3.5.6. Test results of the page loading listed in this table:
