These tests measure network performance when downloading Google P3DT tiles.
Each one uses a slightly different methodology that could yield better / worse result.
The test files are a subset of what's downloaded when running the Cesium for Unreal automation test LocaleChrysler.
It becomes a very useful comparison when running that automation test in Unreal.
It establishes a fastest possible baseline, where we can measure load speed as if there is no other game engine overhead.
- Install Unreal
- Install the Cesium for Unreal plugin and samples project
- Install DB Browser for SQLite
- Install Python
- Optionally install Wireshark
- Start any app that uses Google P3DT
- Could load level 12 from the Cesium for Unreal samples
- Could also run any of the Cesium Google PD3T automation tests
- Find you sqlite cache at
C:\Users\<your username>\AppData\Local\UnrealEngine\5.4 - Open DB Browser for SQLite and open up cesium-request-cache.sqlite
- You'll see many entries. Note the name
https://tile.googleapis.com/... - In the name you should see the
session=somevalueembedded - Copy this session value to
TestKey.py
Note: Sessions don't last forever. You'll have to repeat these steps if running the same tests the next day
- Run any of these
- CurlExeTest.py
- PyRequestLibTest.py
- PyUrlLib3Test.py
- ThreadedRequestsTest.py
- Note the output and the speed detected. You can optionally start a Wireshark session, then run the test, and view the speed results from Wireshark
Note: In TestUtils.py, you'll notice a set of 4 files as the test files to download. These as the first 4 files downloaded when running the Cesium for Unreal "LocaleChrysler". These filenames may get out of date. You might also want to download more / less files. Feel free to edit to your needs
