priority - 10 Eliminate render-blocking JavaScript and CSS in above-the-fold content

Your page has 10 blocking script resources and 2 blocking CSS resources. This causes a delay in rendering your page.

None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.

Remove render-blocking JavaScript:

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 24KiB (44% reduction).

Minifying http://cstc.org.cn/ could save 24KiB (44% reduction).

priority - 2 Prioritize 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.

55.6KiB of the HTML response was required to render the above-the-fold content. This requires 3 network round-trips. However, if the HTML response were compressed, then the HTML required to render the above-the-fold content could be delivered in just 1 network round-trips. Enable compression for the HTML response in order to prioritize the visible content for this page.

Only about 56% of the final above-the-fold content could be rendered with the HTML delivered within 2 round-trips.

priority - 40 Eliminate render-blocking JavaScript and CSS in above-the-fold content

Your page has 3 blocking script resources and 2 blocking CSS resources. This causes a delay in rendering your page.

None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.

Remove render-blocking JavaScript:

http://cstc.org.cn/public/home/js/jquery.min.js
http://cstc.org.cn/public/home/js/lib.js
http://cstc.org.cn/public/home/js/slick.min.js

Optimize CSS Delivery of the following:

http://cstc.org.cn/public/home/css/style.css
http://cstc.org.cn/public/home/css/slick.css

priority - 17 Enable 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 162.8KiB (76% reduction).

Compressing http://cstc.org.cn/public/home/js/jquery.min.js could save 118.4KiB (75% reduction).
Compressing http://cstc.org.cn/public/home/js/slick.min.js could save 40.5KiB (79% reduction).
Compressing http://cstc.org.cn/public/home/js/lib.js could save 4KiB (72% reduction).

priority - 8 Prioritize 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 65% of the final above-the-fold content could be rendered with the full HTML response.

priority - 8 Minify JavaScript

Compacting JavaScript code can save many bytes of data and speed up downloading, parsing, and execution time.

Minify JavaScript for the following resources to reduce their size by 77.3KiB (37% reduction).

Minifying http://cstc.org.cn/public/home/js/jquery.min.js could save 63.6KiB (41% reduction).
Minifying http://cstc.org.cn/public/home/js/slick.min.js could save 11.8KiB (24% reduction).
Minifying http://cstc.org.cn/public/home/js/lib.js could save 2KiB (37% reduction).

priority - 3 Reduce server response time

In our test, your server responded in 0.43 seconds.

There are many factors that can slow down your server response time. Please read our recommendations to learn how you can monitor and measure where your server is spending the most time.

priority - 0 Minify 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 3KiB (23% reduction).

Minifying http://cstc.org.cn/ could save 3KiB (23% reduction) after compression.

cstc.org.cn Ping

Ping is a networking utility tool to test if a particular host is reachable. It is a diagnostic that checks reachability of a host on an Internet Protocol (IP) network. In a computer network, a ping test is a way of sending messages from one host to another. Aside from checking if the host is connected to a network, ping also gives indicators of the reliability and general speed of the connection.

cstc.org.cn TRACEROUTE

Traceroute is a network diagnostic tool used to track the pathway taken by a packet on an IP network from source to destination. Traceroute also records the time taken for each hop the packet makes during its route to the destination. Traceroute uses ICMP (Internet Control Message Protocol) echo packets with variable time to live values. The response time of each hop is calculated. To guarantee accuracy, each hop is queried multiple times (usually three times) to better measure the response of that particular hop.
