Use Latency checker to find out which Stratu.ms location is best for you. Login Register Help center Latency checker. Enter the pool address on which you want to mine and run a quick latency check to find out which Stratu.ms location is. On a USB device, poll rate refers to how often the OS will check the USB device for updates. The poll rate together with the scan rate determines the maximum input latency. For example, take the example above were the scan interval is 5ms. If our poll rate is 1000Hz, then the keyboard is polled every 1ms and so the maximal input latency is 1+5=6ms.

Latency is the amount of time it takes for a computer or application to respond to your request. The less time it takes the better. This is a test where you want to score low and there's a theoretical limit to how low you can go. Zero. Meaning the response was instant. Absolute zero is impossible on this test.

Transmission Control Protocol or TCP is how you're able to see this page right now. The vast majority of your internet communication traverses this reliable, ordered and error-checked delivery of a stream of bytes.

a.k.a. TestMy Latency is not the average ICMP ping you get from your command line. TestMy Latency runs on the Transmission Control Protocol (TCP) (layer 4 - transport) where as normal ping runs on ICMP (layer 3 - network). ICMP is not used to exchange data between systems and has no way of interacting or detecting issues with the layers above it (layers 4 through 7). Your average command line ping simply can't give a full picture of what's happening on layer 4. TestMy Latency is different and tests at the transport layer.

“TCP Segment drops manifest as large increases in delay”

Read this latency test case study posted at stanford.edu on the difference between ICMP ping and TCP ping.

TL;DR TCP has more speed bumps

TestMy Latency is more sensitive than your typical ICMP ping for real connection issues. But both are complimentary to each other. ICMP will show you the best case, TestMy Latency (using TCP) isn't as forgiving. Even running this latency test on great computers with great networks shows that TCP isn't perfect. Don't expect a perfect score. But better computers on better networks always fair much better. Exactly what we like to test here. You can ping the servers from your command line at the same time you're testing to get a comparison. Because there is less to go wrong at the layer ping runs on you can expect a lower result from your command line. Think of it this way, TestMy Latency tests beyond normal ping so there are more variables that can affect the result. Equals higher result.

Hack TestMy Latency

Test using TestMy Latency on your own network. Host any http server, put this file under the folder /b/img/ then call TestMy Latency with the following URL: https://testmy.net/latency?internal=1&addr=[server-address] (e.g. https://testmy.net/latency?internal=1&addr=192.168.1.199) . This tool was first developed running on LAN to eliminate variables. It may be just as useful and helpful validation for your own testing to try a LAN test yourself.

Try different domains. A large majority of popular domains already work with TestMy Latency. Use this syntax https://testmy.net/latency?addr=[domain.name] (e.g. https://testmy.net/latency?addr=youtube.com)

The Future of the Internet is low latency

Lower latency is ultra important, not just your transfer speed. With Starlink Satellite Constellation and the advent of 5G this tool will provide you with a way to test and compare your new found lower latency. Always keep TestMy.net in your mind.

Latency Checker

Small and portable tool that checks system activity for latency issues, to find out if it's capable to handling audio and video real-time streaming without interruptions

DPC Latency Checker is a tiny and portable application that monitors computer activity and verifies if it is able to handle real-time streaming of audio and video data without interruptions. It does not include configuration parameters.

Speedtest With Jitter And Latency

Since installation is not a prerequisite, you can drop the executable file anywhere on the hard disk and click it to run.

It is also possible to move DPC Latency Checker to a USB flash drive or similar storage unit, in order to use it on any machine with minimum effort.

An important aspect to keep in mind is that the Windows registry does not get new entries, and files are not left behind on the hard disk after program removal.

The interface of DPC Latency Checker is based on a standard window that contains a graph which tracks DPC latency. You can view the test interval, current latency, and absolute maximum value. Aside from stopping the monitoring process, you can reset the numerical values. There are no other options available through this tool. For example, you cannot ask DPC Latency Checker to record activity to file.

The simple application does not put a strain on system resources, as it requires a low amount of CPU and RAM to run properly. No error dialogs were shown in our tests, and the tool did not hang or crash. To conclude, DPC Latency Checker offers a straightforward solution to diagnosing computer latency issues with minimum effort.
