B4J Tutorial [IoT] Web Server Performance: Raspberry Pi 2 vs. Intel Edison vs. BeagleBone Black

I ran some tests to check how these boards perform as web servers.

The tests were similar to the tests done here and here.

Data was read and written to a SQLite database in wal mode. See this link for more information: https://www.b4x.com/android/forum/threads/raspberry-pi-2-server-performance.57856/

The boards tested are: Raspberry Pi 2, Intel Edison and BeagleBone Black.
The PC is a quad core PC with SSD drive.

Note that like any performance results you need to take them with a grain of salt.

Test 1 - Handler that writes a short string as the response

RPi 2: >600 rps (requests per second)
Edison: >600 rps
BBB: 300 rps
PC: >600 rps

Test 2 - Handler that reads a random record from the database (based on the primary key)

RPi 2: >600 rps
Edison: >600 rps
BBB: 60 rps
PC : >600 rps

Test 3 - 10% insert, 90% read random record

RPi 2: 300 rps
Edison: 400 rps
BBB: 50 rps
PC: >600 rps

Test 4 - 50% insert, 50% read random record

RPi 2: 100 rps
Edison: 300 rps <-- faster than the PC
BBB: 20 rps
PC: 200 rps

Test 5 - 100% inserts

RPi 2: 50 rps
Edison: 150 rps <-- faster than the PC
BBB: 12 rps
PC: 100 rps

Conclusion

The performance of both the Raspberry Pi 2 and the Edison as web servers is excellent.
The BeagleBone Black board can be good for low - medium traffic solutions.

Note that I wasn't able to get the SQLite engine to run in wal mode on the BBB. It might work if you install Java 8 instead of 7.

anyone have an idea of how different would have been the results with MySQL on PC?

I'm using MySQL and wonder if switching to SQLite would be equivalent or not.

Yes. See these results: https://www.b4x.com/android/forum/threads/server-performance-measures.37502/#content

MySQL is faster for a heavy traffic server.

Could be interesting to see a report with the new PI 3
