axler.net Desktop Speed Test Quick Summary
priority - 7Optimize images
Properly formatting and compressing images can save many bytes of data.
Optimize the following images to reduce their size by 69.7KiB (25% reduction).
Compressing http://axler.net/ChineseTitle.png could save 22.1KiB (79% reduction).
Compressing http://axler.net/new.gif could save 680B (59% reduction).
priority - 2Prioritize visible content
Your page requires additional network round trips to render the above-the-fold content. For best performance, reduce the amount of HTML needed to render above-the-fold content.
The entire HTML response was not sufficient to render the above-the-fold content. This usually indicates that additional resources, loaded after HTML parsing, were required to render above-the-fold content. Prioritize visible content that is needed for rendering above-the-fold by including it directly in the HTML response.
priority - 2Leverage browser caching
Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.
Leverage browser caching for the following cacheable resources:
http://axler.net/SheldonBengalSpotsGGBridge.png (expiration not specified)
http://axler.net/new.gif (expiration not specified)
priority - 0Enable compression
Compressing resources with gzip or deflate can reduce the number of bytes sent over the network.
Enable compression for the following resources to reduce their transfer size by 2.3KiB (58% reduction).

axler.net Ping
Ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. It measures the round-trip time for messages sent from the originating host to a destination computer that are echoed back to the source.
axler.net TRACEROUTE
Traceroute is a computer network diagnostic tool for displaying the route (path) and measuring transit delays of packets across an Internet Protocol (IP) network. The history of the route is recorded as the round-trip times of the packets received from each successive host (remote node) in the route (path); the sum of the mean times in each hop is a measure of the total time spent to establish the connection. Traceroute proceeds unless all (three) sent packets are lost more than twice, then the connection is lost and the route cannot be evaluated.
