You can make private in range
from
0x0000000000000000000000000000000000000000000000000000000000000001
to
0x00000000000000000000000000000000000000000000000031f5c4ed27680000
than make public key(64bytes) from this private key and show me this public key.
You specify this range to prove your speed which is a 62bits range (not 64bits you're right).
If you want to prove your speed, post your code.
Solving ECDLP on sepck1 for a reduced priv key range does not prove the speed you announce.
The speed of a method depend first on the complexity of the used algorithm not only on the speed of the hardware.
