It's only there where's disk activity. For example, if I have 4 or more
torrents downloading. When that happens, typing "mc" (to start midnight

The speed impact on one of my servers (100+ shell users) was dramatic.
10 seconds for a simple "ls /" for example.
It's not like LVM is modelling the universe' operation on your CPU, but
that's where impact should be, while disk activity (and data written)
should be roughly the same, aside from possible fragmentation if you
(re)create lv's on a daily basis, so prehaps it's not the disk but the
cpu where's the real bottleneck is?
I know it's not the CPU since there's 'top' to check this.
