Why same matlab code shows different performance on different server with same RAM and processors?
Below are the server configuration: Code runs 10 times faster on Serve1 than on Server2.
Server1: Windows Server 2008 R2 Enterprise, Intel® Xeon® CPU ES-2697 v2 @2.70GHz 2.70 GHz(8 processors),128GB RAM
Server2: Windows Server 2016 R2 Enterprise, Intel® Xeon® CPU ES-2670 v3 @2.30GHz 2.29 GHz(8 processors),128GB RAM

The processors are different. The E5-2670 v3 has AVX2, but the ES-2697 v2 has not. But this should not result in a factor of 10.
How did you test the performance? Does any other application run on the slower server? Can you identify the bottlenecks of your code and post them?
