Benefits may greatly varry.

For this slowest 2+GHz 8 core server of the world make that 5 minutes
48 seconds to 5 minutes 30 seconds here or 5% speed increase. And yes,
this slowest 2+GHz 8 core server of the world does take that long to
boot, mainly bios ram test and scsi probing. Never seen a server count
its ram so slow.

And you get that once or twice a year. Not sure if the risk of
breaking things is worth that optimization.
