I am considering setting up an LVM. Does this cause a performance hit for real
time audio file accesses?

i've been using lvm-based partitioning for a long time now, and have
never had problems. but it never occurred to me to do a/b measurements
either.
in any case, i don't see how it could have an impact (and if it did,
that would probably be considered a bug by the kernel crowd and get
fixed real quick).

one thing to investigate is data recovery in
the case of hardware failure.
TEST: remove a hard drive from your system,
put it in some other system, and try to recover
the data.
it may be that LVM encodes the filesystem
such that recovery must be through the LVM
software that was managing the data input.

It does have an impact but I don't have numbers to tell you how big it
is. In testing different configurations on servers I have found that a
filesystem running on top of a raid array is faster than a filesystem
running on top of LVM on a raid array.
