The Design and Implementation of laffer1

Anything before 2.6.33 doesn't support 4K very well. Distros with tools dated after April, 2010 can handle alignment of 4K drives properly.

Performance issues exist with the defaults selected in FreeBSD. Matt Dillon made some comments about what to do with UFS to get it to perform well.

This program lets you test performance differences with different alignments (sectors) of the drives in FreeBSD and MidnightBSD.

This patch makes Glabel align properly when using a certain flag for 4k drives.
