Let's actually try that. If you have the ibmtss installed, the command
to time primary key generation from userspace on your tpm is
time tsscreateprimary -hi n -ecc nistp256
And just for chuckles and grins, try it in the owner hierarchy as well
(sometimes slow TPMs cache this)
time tsscreateprimary -hi o -ecc nistp256
And if you have tpm2 tools, the above commands should be:
time tpm2_createprimary -C n -G ecc256
time tpm2_createprimary -C o -G ecc256
