Correct me if I am wrong, but with lvm you do not have
control over physical placement of your partitions. Right?
So if you use lvm even for swap, lvm might place it anywhere
on disk, on the beginning (first cylinders, highest speed,
i.e. ~50 MB/s) or at the end (in my case ~30 MB/s).

Utilities like hdtach (win-world, I do not know something
equivalent for linux) show, that read/write speed is not
constant over the whole disk (number of sectors on outside
cylinders is much higher, than on the inside cylinders).

In some cases it might matter to partition disk wisely,
for example when someone is doing tv/video grabbing, he
needs maximum transfer speed to avoid frame-dropping, so
it might be worth putting /home or /tmp somewhere near
beginning of disk (outside cylinders).  Similar for swap,
plus optimising of head-movement, etc...

Just my 2 cents, but personally I'm using lvm too...
