Some of you may remember me as the guy who made the Twitch Analyzer tool. Quick screenshot and annotation tool for mac. I've just released a new tool called TwitchTest that will test your bandwidth to the various Twitch ingest servers.

Our embedded VPN speed test uses the Speedify VPN servers directly to test the bandwidth and latency of the connection for each adapter (WiFi, cellular, Ethernet, etc.) you’re using, and then for the combined connection of the 2 or more network adapters.

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

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.

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.

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

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.

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.

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.

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.

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.

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.

Bandwidth tester for Twitch

TwitchTest creates a test stream to Twitch, using the '?bandwidthtest' option so your channel doesn't actually go live. It will attempt to stream at up to 10 mbps and show the achieved bitrate for each server. An estimation of the connection quality is presented, which is based on the number of retransmissions required and how consistent the delay between consecutive sends are. A connection quality of 80+ is recommended for a reliable stream. The TCP window size (SO_SNDBUF) can be adjusted to see what effects it has, the default setting matches what is used in OBS.

Requires Administrator privileges to run, as the Windows TCP connection metrics API is only available to applications running as administrator.

A pre-compiled binary for Windows can be downloaded at https://r1ch.net/projects/twitchtest.
