Download Meteor app speed test for Windows 8/8.1/10/7/XP/Vista & Mac. The Meteor app speed test is currently restricted for smartphones only. In order to get Meteor for Windows or Meteor for Mac, there is an elaborate procedure that one must follow to accomplish this task.
If you have a Mac, there is no need to download new software to test your LAN speed. Mac OS X Snow Leopard, Lion and Mountain Lion computers include a built-in Network Utility that will test your network speed for you. This little-known utility is buried in the Application's Utilities folder. Network Utility can also provide you with a wealth of information about your network, your Internet service and websites. Much of this is not very useful except to trained network administrators, but there are a few gems included that can give you some insight into the health of your office network and even the status of your company website.
Testing LAN Speed
1.Launch Finder on your Snow Leopard OS X 10.6.8 Mac. Click the 'Applications' folder, then open the 'Utilities' folder. Double-click the 'Network Utility' application.
2.Click the 'Network Interface' drop-down menu under the Info tab and select your network. To test the speed of a LAN, select 'Ethernet.' Select 'Wi-Fi' to test a Wi-Fi network or WLAN. The 'Bluetooth' option is for testing bluetooth modems.
3.Look at the number beside Link Speed. This is the speed of your network, measured in Megabits per second, such as '144 Mbit/s.' If the Link Speed displays '0 Mbit/s,' and the Link Status below it is 'Inactive,' you are not connected to the network. Make sure your Ethernet cable is connected to your Mac.
Other Network Utility Tools
1.Look at the Info tab on the Network Utility application if you ever need to know your computer's MAC or Hardware Address or IP Address. This information helps a network administrator to identify your computer on the network while troubleshooting a server or router.
2.Look at the Transfer Statistics section on the right. If the network is active, you will see an increasing number of sent and received packets. These statistics also display network errors and network data collisions. Collisions and errors can be caused by defective or misconfigured network equipment or interference caused by cell phones and microwaves.
3.Click the 'Ping' tab and enter an IP address or website URL to determine whether or not your Mac can access a server or website. Pings act much like a submarine SONAR ping. Your computer sends a series of pings to the other computer and measures how long it takes to come back. This is often a quick way to determine if a website or your Internet service is down.
4.Click the 'Traceroute' tab and enter an IP address or website URL to see the network nodes between your computer and the server. If the Traceroute stops shortly after listing your computer IP address, there is usually a problem with your network or Internet service. If it fails after several network hops, which usually also show the cities where the nodes are located, the problem is usually on the other end, like the website server or its network.
5.Click the 'Netstat' tab when performing advanced network diagnostics or troubleshooting. This tab shows routing table information, detailed statistics for each protocol used, like IP, UDP and IPSEC, as well as multicast information and network socket connections.
6.Click the 'Whois' tab to find out information about a website or Internet domain. Type the website URL or IP address in the text field and then click the 'Whois' button. If your company owns an IP address or website domain, this information tells you if your contact information is updated, unless you have opted to hide it from the public. It also shows you when the domain was first registered, last registered and when it's due to expire.

#ChromeDevSummit
this year? Catch all the content (and more!) in the Chrome Dev Summit 2019 playlist on our Chrome Developers YouTube Channel. Lighthouse is an open-source,automated tool for improving the quality of web pages. You can run it againstany web page, public or requiring authentication. It has audits for performance,accessibility, progressive web apps, SEO and more.
You can run Lighthouse in Chrome DevTools, from the command line, or as aNode module. You give Lighthouse a URL to audit, it runs a series of auditsagainst the page, and then it generates a report on how well the page did.From there, use the failing audits as indicators on how to improve the page.Each audit has a reference doc explaining why the audit is important, aswell as how to fix it.
You can also use Lighthouse CI to prevent regressions on your sites.
Check out the video below from Google I/O 2019 to learn more about how to useand contribute to Lighthouse.
Get started
Choose the Lighthouse workflow that suits you best:
- In Chrome DevTools. Easily audit pages that require authentication,and read your reports in a user-friendly format.
- From the command line. Automate your Lighthouse runs via shell scripts.
- As a Node module. Integrate Lighthouse into your continuousintegration systems.
- From a web UI. Run Lighthouse and link to reports withoutinstalling a thing.
Run Lighthouse in Chrome DevTools
Lighthouse powers the Audits panel of Chrome DevTools. To run a report:
- Download Google Chrome for Desktop.
- In Google Chrome, go to the URL you want to audit. You can audit any URL on the web.
- Open Chrome DevTools.
- Click the Audits tab.
- Click Perform an audit. DevTools shows you a list of audit categories.Leave them all enabled.
- Click Run audit. After 30 to 60 seconds, Lighthouse gives you a reporton the page.
Install and run the Node command line tool
To install the Node module:
- Download Google Chrome for Desktop.
- Install the current Long-Term Supportversion of Node.
- Install Lighthouse. The
-g
flag installs it as a global module.
To run an audit:
To see all the options:
Run the Node module programmatically
See Using programmatically for an example of running Lighthouseprogrammatically, as a Node module.
Run Lighthouse as a Chrome Extension
Note: Unless you have a specific reason, you should use the Chrome DevTools workflowrather than this Chrome Extension workflow. The DevTools workflow allows for testing localsites and authenticated pages, while the extension does not.To install the extension:
- Download Google Chrome for Desktop.
- Install the LighthouseChrome Extension from the Chrome Webstore.
To run an audit:
- In Chrome, go to the page you want to audit.
- Click Lighthouse . It shouldbe next to the Chrome address bar. If not, open Chrome's main menu andaccess it at the top of the menu. After clicking, the Lighthousemenu expands.
- Click Generate report. Lighthouse runs its audits against thecurrently-focused page, then opens up a new tab with a report of theresults.
Run PageSpeed Insights
To run Lighthouse on PageSpeed Insights:
- Navigate to PageSpeed Insights.
- Enter a web page URL.
- Click Analyze.
Share and view reports online
Use the Lighthouse Viewer to view and share reports online.
Share reports as JSON
The Lighthouse Viewer needs the JSON output of a Lighthouse report. Thelist below explains how to get the JSON output, depending on whatLighthouse workflow you're using:
- Chrome DevTools. Click Download Report .
- Command line. Run:
lighthouse --output json --output-path <path/for/output.json>
- Lighthouse Viewer. Click Export > Save as JSON.
To view the report data:
- Open the Lighthouse Viewer in Google Chrome.
- Drag the JSON file onto the viewer, or click anywhere on the Viewer toopen your file navigator and select the file.
Share reports as GitHub Gists
If you don't want to manually pass around JSON files, you can also share yourreports as secret GitHub Gists. One benefit of Gists is free version control.
To export a report as a Gist from the report:
- (If already on the viewer, skip this step) Click Export > Open In Viewer. The report opens in theViewer, located at
https://googlechrome.github.io/lighthouse/viewer/
. - In the Viewer, click Share . Thefirst time you do this, a popup asks permission to access your basicGitHub data, and to read and write to your Gists.
To export a report as a Gist from the CLI version of Lighthouse,just manually create a Gist and copy-paste the report's JSON outputinto the Gist. The Gist filename containing the JSON output must end in
.lighthouse.report.json
. See Share reports as JSON for an example ofhow to generate JSON output from the command line tool.To view a report that's been saved as a Gist:
- Add
?gist=<ID>
to the Viewer's URL, where<ID>
is the ID of the Gist.https://googlechrome.github.io/lighthouse/viewer/?gist=<ID>
- Open the Viewer, and paste the URL of a Gist into it.
Lighthouse extensibility
Lighthouse aims to provide guidance that is relevant and actionable for all web developers. To this end, there are two features now available that allow you to tailor Lighthouse to your specific needs.
- Stack Packs. Many developers today use different technologies (backend/CMS/JavaScript frameworks) to build their web pages. Instead of only surfacing general recommendations, Lighthouse is now able to provide more relevant and actionable advice depending on the tools used.
Stack Packs allow Lighthouse to detect what platform your site is built on and display specific stack-based recommendations. These recommendations are defined and curated by experts from the community.
To contribute a Stack Pack, review the Contributing Guidelines.
- Lighthouse Plugins. Lighthouse Plugins allow domain experts in the community to extend the functionality of Lighthouse for their specific needs. You are now able to leverage the data that Lighthouse collects to create new audits. At its core, a Lighthouse plugin is a node module that implements a set of checks that will be run by Lighthouse and added to the report as a new category.
For more information about how to create your own plugin, check out our Plugin Handbook in the Lighthouse GitHub repo.
Contribute to Lighthouse
Lighthouse is open source and contributions are welcome.Check out the repository's issue trackerto find bugs that you can fix, or audits that you can create or improve upon.The issues tracker is also a good place to discuss audit metrics, ideas fornew audits, or anything else related to Lighthouse.
