[ZODB-Dev] Packing much improved with Relstorage 1.5

[Anthony Gerrard]

Some results I thought some people might be interested following our
upgrade from Relstorage 1.4.1 to 1.5.  I've only upgraded our test
system but that is a clone of live with a db size of 6631MB running
Plone 3.3.

Before the upgrade the pack was taking 2 hours 15 minutes.  After the
pack 8 minutes.

Fantastic work.  Thanks!

Anthony
