Just because I set the SATA mode to AHCI w/o Legacy mode...
I might guess that the IDE interrupts are more costly while SATA/SCSI
ones are more offloaded to hardware, leaving your CPUs more available
and responsive for small urgent tasks?
In fact, even for VMs it is a stated reason to prefer SATA/SCSI vHBAs
to IDE ones, except for maybe rarely used vCDROMs.
Maybe it's just that sometimes the Byte Fairy is generous.
Yup, that's the more likely explanation :)
