Got a chance to grab 8 dedicated servers. All of them are identical configuration.
- Intel Xeon E5-2660 2.20 GHz – 8 Core / 16 Threads
- 16GB (DDR3) Memory
- 240GB (SSD) Storage
- 1 Gbps Network Port
And I put Debian on 2 of them and Ubuntu 2 of them. Since I use these servers for computation, I tested all of them by running Intel LINPACK Benchmark.
The results:
Ubuntu 16.04.2 / Linux 4.4.0

Now, can anyone tell me why Debian is slower ? .. hmm
