Test results for specific latencies

All tests in this topic were done on consumer-grade equipment in available networks during normal hours of network load.

The testing platform was built from following components:

  • Desktop computer with Intel Core i7 CPU running Windows 10, connected to networks
  • Nexus 6P mobile device running Android 7, connected to networks

Connections to the following lab servers were used:

  • Cloud server
  • Local virtual machine server

Connection types used:

  • Local Virtual LAN
  • LAN/WAN
    Speed: in 30.01Mbps, out 29.93Mbps
  • Wi-Fi
    Speed: in 10.24Mbps, out 1.03Mbps
  • 4G LTE
    Speed: in 15.82Mbps, out 4.93Mbps
  • 3G HDSPA
    Speed: in 3.34Mbps, out 0.64Mbps
  • 2G EDGE
    Speed: in 0.18Mbps, out 0.14Mbps

Codec results

Process Average (ms) Min (ms) Max (ms) Size (bytes) Count
Opus encoding 4.503 1.382 5.086 2880 17
Opus decoding 0.571 0.210 0.765 109 17

In this table, Average, Min and Max mean the average, minimum and maximum time it took to encode or decode a data packet. Size is the size of the packet, and Count is the number of encoding and decoding operations done for the test.

Encryption results

Process Average (ms) Min (ms) Max (ms) Size (bytes) Count
UDP encryption 0.018 0.010 0.023 7 9
UDP decryption 0.018 0.011 0.024 13 9

In this table, Average, Min and Max mean the average, minimum and maximum time it took to encrypt or decrypt a data packet. Size is the size of the packet, and Count is the number of encryption and decryption operations done for the test.

Audio processing results

Measurement Average (ms) Min (ms) Max (ms) Size (bytes) Count
From microphone to sendable packet 0.832 0.014 5.563 960 100
From received packet to jitter buffer 0.061 0.026 0.199 120 17
From data acquisition to jittered speaker output 0.754 0.292 1.304 3840 29

In this table, Average, Min and Max means the average, minimum and maximum time it took to a data packet to complete the path for a measurement. Size is the size of the packet, and Count is the number of measurements done for the test.

Network time results

In the following charts, Average, Min and Max mean the average, minimum and maximum time it took to a data packet to be transferred over the network; lower means faster. Count is the number of measurements done for the test.
