Undo was no longer an option

Truncating the Data.fs (removing all transactions since, including the offending one)

undesirable

small additional buildout configuration file

tells Zope not to try and write product information to the ZODB

because zc.beforestorage puts your ZODB in read-only mode

<zodb_db main>    # Main database    cache-size 650000%import zc.beforestorage%import relstorage <before> before 2008-12-08T10:29:03    <relstorage>        <oracle>            dsn RELSTORAGE_DSN            password xxxxxxxxx            user xxxxxxxx        </oracle>    </relstorage> </before>    mount-point /</zodb_db>

Plone 4 is about to

enter beta testing prior to a final release

performance

what does all this mean?  Well, honestly, not much

realistic sample content

very, very proud of Plone’s raw speed

suspect MAMP not to be very efficient

the difference is down to Plone’s use of the ZODB

Contrast this to the PHP/MySQL systems which must perform several selects in order to render the page

ZODB fetches are serial

addressed as part of Dexterity

fundamental architectural difference

CMSes that use the RDBMS and some kind of ORM or manual SQL (like Drupal, Joomla)

those that use an OODBMS such as Plone

‘out of the box’ speed, since that is something a lot of people historically have not liked about Plone

our installer sets up ZEO with clients for you, so this is “out-of-the-box”

counter the (incorrect) perception out there that “Plone is slow”
