Hmm, I've not heard or seen anything about LVM partitions taking more
resources (or time) to access.  When I've used it on Solaris systems,
its actually sped up services that were disk I/O intensive (I assumed
because the requests were spread across multiple disks). 

Just to be safe though, I reformatted the system this morning and moved
the Swap to it's own partitions (on three different drives).
