the rootmarks are normalized to a reference machine. So the compiled
and interpreted version although different in real time produce more
or less equal rootmarks.
Could you tell me also which I/O system your PII 450 has (SCSI, ultra-wide
SCSI, UATA, disk rpms, etc). I've a dual PII 450 with UATA 7200rpm disk at
home so I will make the comparison this evening.
Cheers, Fons.
