Description Milan Broz 2008-06-25 05:09:32 EDT
+++ This bug was initially created as a clone of Bug #261521 +++
RHEL5 clone

Basic issue is pvdisplay is taking an unreasonably long time and consuming an
unreasonably large amount of RAM.

-- Additional comment from mbroz@redhat.com on 2008-02-01 10:12 EST --
There are basically two steps to speed up this process we are working on
1) use internal cache for device labels
2) use internal cache for metadata areas
