optimizing disk performance

optimizing disk performance
I have some questions regarding disk perfomance, and what I can do to make it just a little (or much 
) more faster.
From what I've heard the first partitions will be faster than the later ones because tracks at the outer edges of a hard drive platter simply moves faster. But I've also read in a book that most-used partitions should be placed in the middle of a range of partitions. This doesn't make much sense to me.
Does this "put-heavily-accessed-in-the-middle" thing apply to logical partitions?
Should the heavily accessed partition really go in the middle? Even if the first partitions are large in size and later are small, thus leaving the heavily accessed partition "nearer" the center (where the platter moves slower)... ?
Any other suggestions like partition layout, filesystem recommendation etc are highly appreciated
I'm working with a linux system using a server software that does a lot of reading and writing so every bit of speed I can gain is valueable.
Thanks in advance

partitio
PARTITION(8) System Manager's Manual PARTITION(8) NAME
partition - make a partition table SYNOPSIS
partition [-mf] device [type:]size[+*] ... DESCRIPTION
Partition makes a partition table on device using the types and sizes given. It may be used in combination with repartition(8) for auto- matic installation of Minix. You may give up to four type:size[+*] specifications for the partitions. You may also specify holes before, between, and after the parti- tions. A hole differs from a partition specification by not having a type. The first hole is by default 1 sector to make space for the primary bootstrap and the partition table. The other holes are 0. The type field is the type of the partitition in hexadecimal. The size field is the partition's size in sectors. The + or * may option- ally be added to indicate that the partition must be expanded to contain any leftover space on the device or to mark the partition active. Partitions are padded out to cylinder boundaries, except for the first one, it starts on track 1. Some operating systems care about this. Minix and MS-DOS do not. OPTIONS
-m Minix only, no need to pad partitions. This is the default for subpartition tables. -f Force making a partition table even if the device is too small. EXAMPLE
partition /dev/hd0 01:16384 81:40000 81:2880* 06:20000+ Partitions disk 0 into an 8 Mb DOS partition, 20 Mb Minix /usr, 1.44 Mb Minix / (active), and a DOS partition of at least 10 Mb at the end of the disk. (06:0+ would have been ok too, it's just a sanity check.) SEE ALSO
