Flexibility is often expensive from a performance point of view.  We
regularly tell people here that they have to avoid using Linux's LVM for
similar reasons--while it shouldn't be so slow, it is.  Nothing you can
do about it but use direct disk partitions instead if you need the
performance to be good.
