44 The swap partitions on the drives should be approximately the same size.
48 the swap partitions near the same size will allow the kernel to optimally
63 partitions are read-mostly, with very little writing, while
68 heavily write-loaded partitions will not bleed over into the mostly-read

138 atime turned on for mostly read-only partitions such as
148 In larger systems you can stripe partitions from several drives together
159 speaking, striping smaller partitions such as the root and
161 or essentially read-only partitions such as
164 You should only stripe partitions that require serious I/O performance,
167 or custom partitions used to hold databases and web pages.
170 File systems tend to store meta-data on power-of-2 boundaries
173 means you want to use a large off-center stripe size such as 1152 sectors
174 so sequential I/O does not seek both disks and so meta-data is distributed
