You probably won't notice any difference.  I've been running Fedora
for years and the installer sets up /home and / as separate volumes in
an LVM.  Presumably it's for convenience and has no performance
implications.  Back in the SAN days (I'm a sysadmin in real life) I
used to use LVM to stripe across LUNS accessed from a SAN and share
the filesystems out to 100's of NFS clients.  In those cases the
biggest performance factors were the disk array, the filesystem or the
NFS protocol itself.  IMHO LVM is a mature product and if setup
correctly shouldn't cause you any problems.
