priority - 9Avoid landing page redirects

Your page has 2 redirects. Redirects introduce additional delays before the page can be loaded.

Avoid landing page redirects for the following chain of redirected URLs.

http://algebra.com/
https://algebra.com/
https://www.algebra.com/

priority - 8Eliminate render-blocking JavaScript and CSS in above-the-fold content

Your page has 4 blocking script resources. This causes a delay in rendering your page.

Use asynchronous versions of the following scripts:

priority - 7Leverage 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:

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.

Only about 53% of the final above-the-fold content could be rendered with the full HTML response.

priority - 0Optimize images

Properly formatting and compressing images can save many bytes of data.

Optimize the following images to reduce their size by 3.9KiB (61% reduction).

Losslessly compressing https://www.algebra.com/images/tabs/tabs-middle-off-onleft-long.gif could save 1.1KiB (60% reduction).
Losslessly compressing https://www.algebra.com/images/tabs/tabs-middle-off-long.gif could save 1.1KiB (57% reduction).
Losslessly compressing https://www.algebra.com/images/tabs/tabs-left-on-long.gif could save 1KiB (63% reduction).
Losslessly compressing https://www.algebra.com/images/tabs/subnav-bg.gif could save 734B (66% reduction).

priority - 0Minify HTML

Compacting HTML code, including any inline JavaScript and CSS contained in it, can save many bytes of data and speed up download and parse times.

Minify HTML for the following resources to reduce their size by 818B (11% reduction).

Minifying https://www.algebra.com/ could save 818B (11% reduction) after compression.

algebra.com 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.


algebra.com 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.
