No, wrong, I am sorry :-D You might let LVM choose where to put the extends for a newly created logic= al=20 volume, but you might also tell LVM where to put it. > 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).

Correct, but then - does the performance of your system really depend on th= e=20 speed of your swap device? If so, consider upgrading RAM. You will *never*= =20 get swap devices so fast that it is really pleasurable to work with them. > 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... Again, see above. Regards Martin =2D-=20 Dipl. Wirtsch.Inf.(Univ.)
