Dear GetDP community,

I recently faced a problem that simulations on a PC with a Xeon processor
are much slower.
Two pcs I have compared are:
i7-4970 3.6GHz, 32 GB RAM, Windows 10
Xeon 5222 3.8GHz,  128 GB RAM, Windows 10
I have run a single-threaded simulation with slightly modified cohomology
example using MUMPS direct solver.
The problem is that simulations on Xeon are approximately 1.5 times slower.
Do you have any idea what could be wrong?

Best regards,
Vadims
