priority - 12 Eliminate render-blocking JavaScript and CSS in above-the-fold content

Your page has 7 blocking script resources and 4 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:

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://costco.co.kr/
https://costco.co.kr/
https://www.costco.co.kr/

priority - 4 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 29% of the final above-the-fold content could be rendered with the full HTML response.

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

Your page has 7 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:

https://costco.co.kr/_ui/shared/js/analyticsmediator.js
https://costco.co.kr/_ui/responsive/common/js/jquery_extensions-min.js
https://costco.co.kr/_ui/shared/js/generatedVariables.js
https://costco.co.kr/_ui/responsive/common/bootstr…st/js/bootstrap.min.js
https://costco.co.kr/_ui/responsive/common/js/acc-min.js
https://costco.co.kr/_ui/addons/buynowaddon/respon…mmon/js/buynowaddon.js
https://costco.co.kr/_ui/responsive/common/js/costco.lib.js

Optimize CSS Delivery of the following:

https://costco.co.kr/_ui/responsive/theme-costco/css/style-min.css
https://costco.co.kr/medias/sys_master/h0a/h63/9094836912158.css

priority - 16 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 21% of the final above-the-fold content could be rendered with the full HTML response.

priority - 12 Leverage 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:

https://developers.kakao.com/sdk/js/kakao.min.js (expiration not specified)
https://pgweb.uplus.co.kr:9091/WEB_SERVER/js/receipt_link.js (expiration not specified)

https://costco.co.kr/medias/sys_master/h0a/h63/9094836912158.css (16.8 hours)

priority - 1 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 8KiB (75% reduction).

Compressing https://pgweb.uplus.co.kr:9091/WEB_SERVER/js/receipt_link.js could save 7.4KiB (79% reduction).
Compressing https://spi.maps.daum.net/imap/map_js_init/postcode.v2.js could save 598B (45% reduction).

priority - 0 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 3.5KiB (38% reduction).

Minifying https://pgweb.uplus.co.kr:9091/WEB_SERVER/js/receipt_link.js could save 3.5KiB (38% reduction).

priority - 0 Minify CSS

Compacting CSS code can save many bytes of data and speed up download and parse times.

Minify CSS for the following resources to reduce their size by 1.7KiB (16% reduction).

Minifying https://costco.co.kr/medias/sys_master/h0a/h63/9094836912158.css could save 1.7KiB (16% reduction) after compression.

costco.co.kr 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.


costco.co.kr 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.
