BTW just three days ago eigensym was switched to a different Lapack

background function I think, so maybe we should try a brand new snapshot
for this.

It could always be that openblas has different optimizations for
different Lapack functions for your newer CPU.

Using 2020a-git (2020-01-08) returns the same times. Also I run the script from either the desktop location or from the hard disk. No other program is running etc.

I attach my $sysinfo

? eval $sysinfo
bundle anonymous:
nproc = 12
blascore = "Haswell"
hostname = "DESKTOP-OFGVHSS"
os = "windows"
mpi = 0
blas = "openblas"
omp_num_threads = 12
ncores = 6
omp = 1
blas_parallel = "OpenMP"
mpimax = 12
wordlen = 64

if it could be of any value
