Trailmakers lag: what the numbers mean

A speed test measures bandwidth. This test measures stability: whether small packets arrive, and whether they arrive on time.

Games, voice calls and video calls send small packets many times per second. When some go missing (packet loss) or arrive unevenly (jitter), you get rubber-banding, choppy audio and disconnects, even on a fast line. This test sends small UDP packets to one of four servers, in Frankfurt, New York, San Jose and Singapore, and draws every round trip on the chart.

30 Hz one update every 33.3 ms

What this test sends: 30 packets per second of 200 bytes, matching Trailmakers rather than a generic ping. estimated

Reading the Chart

Ping (latency)

The time a packet needs to the server and back. The line is blue when it is low, yellow when it rises and red when it is high. For most games, under 50 ms is good.

Packet loss

Packets that never came back, shown as red vertical lines. A healthy line loses none. From about 1%, games stutter and drop inputs.

Jitter

How much the ping varies. Under 10 ms is fine for games and calls; more causes stutter and robotic voice. The jitter test page explains the number in detail.

Common Problems and What Helps

1. High ping

Symptom: everything reacts late, in games and on websites.

Distance: you are measuring against a far-away server.
Fix Choose the nearest location in the server field above.
Busy line: downloads or streams fill the router queue.
Fix Pause them, or turn on SQM or QoS in the router. The bufferbloat test measures how much delay they add.

2. High jitter

Symptom: robotic voice in calls, other players stutter and jump in games.

Wi-Fi: walls, neighbouring networks and other devices disturb the signal.
Fix Test once on a cable. If that is clean, stay on the cable or use the 5 GHz band.
Router: an old or overheating router handles packets unevenly.
Fix Restart it. If jitter stays high on every device, replace it.

3. Packet loss

Symptom: calls drop, games rubber-band or disconnect.

Cable: a damaged network cable drops packets without any error message.
Fix Replace it; Cat 6 is enough.
Provider: if loss remains on a cable with nothing else running, the problem is outside your home.
Action Let the test run until it happens, then send the PDF report to your provider.

What Else the Tool Does

Runs as long as you need: leave it open to catch drops that happen now and then. See the ping stability test.
Timeline: drag the bar under the chart back to the moment of a spike.
Notes: click the chart to mark an event before you export it.
Four servers: Frankfurt, New York, San Jose and Singapore.

CSV export: the raw data at 100 ms resolution.
PNG export: the chart as an image, with your notes.
PDF report: times, route and every loss event, without your IP address.
Permanent link: every saved test gets an address you can share.

Frequently Asked Questions

Why is my internet fast on a speed test but bad for gaming?

A speed test measures how much data fits through your line. Games need small packets to arrive on time. A fast line can still lose packets or deliver them unevenly, and a speed test does not show that. This test does.

What is an acceptable amount of packet loss?

0% is normal. A single lost packet over several minutes is not a problem. From about 1% you notice it: games stutter and drop inputs, calls break up.

How do I fix robotic audio on Zoom or Discord?

Robotic audio usually comes from jitter, most often caused by Wi-Fi. Connect with a cable or switch to the 5 GHz band, and pause large downloads during the call.

How can I prove to my ISP that my connection drops?

Leave this test running until the problem happens. Then open the result and download the PDF report. It shows the times, the route and every loss event, and contains no IP address.

Is my lag caused by my Wi-Fi or my ISP?

Run the test on Wi-Fi, then on a cable. If the cable result is clean, Wi-Fi is the cause. If both show loss or spikes, the problem is your router or your provider.

How do I find problems that only happen sometimes?

Leave the test open in a background tab. After 60 seconds it counts every dropout longer than one second. Afterwards, drag the timeline to the moment it happened.

Packet Loss Test for Your Game

Every online game sends updates at its own rate, the tick rate. A test at the wrong rate can miss the lag you are trying to find. Pick your game for a test at its real rate.
