MathNet.Numerics.MKL.Win v2.3.0 performance

(Petter T) #1

After updating from 2.2.0 to 2.3.0 my application goes from using about 1-5% of my CPU to 30-100%. Are there any changes between these versions that are known to cause something like this? I have attached a screenshot of a CPU-profile of the application for v2.3.0, which shows that the CPU spends its time within libiomp5md.dll->KernelBase.dll.

For now I have rolled back to 2.2.0.
