Let’s get Plone 3 support for Plone4ArtistsVideo

February 4, 2008

I am starting an active support to Plone4ArtistsVideo because I like this product. More, I think Plone 3 and beyond needs it as an important add-on. It means we can all reuse its pieces in our projects.

Thanks to Nate Aune for starting this effort. I just pledged to help make that happen.

Then I am going to contribute, at least by testing and documenting (not sure if it was already done) how you can use it as part of your development (integrating, adaptation/subtyping and all).


Improving your Plone site’s performance

September 17, 2007

Plone experts know this. But the others need to know it too. After all, we’re all on the same boat !

You’re in the testing phase of your Plone project, and you find it slow ? Take the following corrective actions, and stop worrying !

  • Use a ZEO-based setup. This is important ! You can distribute the load on 2 or more ZEO clients. (Note that the ZEO server and clients can all be on the same machine.)
    It is possible to bind a ZEO client to a special type of requests such as “content contribution requests”. This way, you keep the other ZEO client(s) responsive for the “normal” requests.
    If you need automatic load balancing, add a load-balancer software such as Pound in front of the ZEO clients.
  • Take advantage of Zope’s HTTP Cache Managers.
    • A simple fix you can do for Plone 2’s default HTTP Cache Manager ; go on the HTTPCache object, and uncheck the “Cache anonymous connections only?” option. There is no reason you should not cache static content such as skin images/files for Authenticated users.
    • Invest a little more to go further with CacheFu-based caching policy management tools.
  • Install a Squid proxy-cache. It is recommended to serve the site with Zope behind Squid (or Zope behind Squid behind Apache).
    There is also Varnish as an alternative to Squid, though I haven’t yet tested it.

Started using OpenID

August 28, 2007

In about 10 mn, I created my account @ claimID.com, and then tested by logging on twitterfeed.com and adding the feed of my blog for the twitter account I created a couple of days ago. We’ll see how it works !

Next thing to do : test it on a Plone 3.0 site (which has support for OpenID OOTB.) Yeah !
