Liferay 6 Performance

08 Mar

Liferay has released performance whitepapers for both Liferay 5 and Liferay 6.  I got a chance today to review Liferay 6 specs and it looks like they have made some significant strides in performance.  Before I point you to the white papers or take two diagrams for comparison, keep in mind that performance on any portal is completely dependent on how you are using it.  Cached content on a portal is fast.  Pulling data from back end systems whose latency is not under your control will probably not be as fast.    You can find the white papers here.

The key findings of the study are:
1. As an infrastructure portal, Liferay Portal can support over 11000 virtual concurrent users on a single server with mean login times
under ½ a second and maximum throughput of 300+ logins per second.
2. In collaboration and social networking scenarios, each physical server supports over 5000 virtual concurrent users at average transaction
times of under 800ms.
3. Liferay Portal’s WCM scales to beyond 150,000 concurrent users on a single Liferay Portal server with average transaction times
under 50ms and 35% CPU utilization.
4. Given sufficient database and efficient load balancing, Liferay Portal can scale linearly as one adds additional servers
to a cluster.

The following charts are throughput based on simple content portlets. (e.g. very light)

IBM Content Manager Collaboration Edition V8.5 announced – features Lotus Quickr 8.5

07 Mar
Lotus Quickr

IBM's Lotus Quickr/FileNet and Lotus Quickr/Content Manager bundles have now been upgraded to use the latest version of Quickr, 8.5.  The newest releases of FileNet (5.0) and Content Manager (8.4.2) are also included:
IBM FileNet Content Manager Collaboration Edition and IBM Content Manager Collaboration Edition offer you the integration between IBM's Lotus Quickr team collaboration and Enterprise Content Management (ECM) family of offerings.

IBM FileNet Content Manager Collaboration Edition V8.5 and IBM Content Manager Collaboration Edition V8.5 deliver updated versions of IBM Lotus Quickr 8.5, IBM FileNet Content Manager V5.0, and IBM Content Manager 8.4.2 to provide integrated end-to-end collaboration and ECM solution that allow users to:
  • Easily move content to and from Lotus Quickr and IBM ECM repositories
  • Benefit from enhanced integration between Lotus Quickr, IBM FileNet Content Manager, and IBM Content Manager, including new "direct connect" web-based component so users can natively display and interact with ECM content from within a Lotus Quickr place
  • Search FileNet Content Manager and IBM Content Manager content from Lotus Quickr Web 2.0 user interface
  • Use the Lotus Quickr connectors to interact with content in both Lotus Quickr, FileNet Content Manager, and IBM Content Manager software, providing access to these repositories as a natural extension of popular applications such as Microsoft Office, Windows Explorer, Outlook, Lotus Notes, Lotus Sametime, and Lotus Symphony

IBM FileNet Content Manager Collaboration Edition and IBM Content Manager Collaboration Edition both extend ECM services and function to a broader audience, while introducing collaborative tools to the content management environment helping organizations connect the right people with the right information at the right time.

IBM FileNet Content Manager Collaboration Edition and IBM Content Manager Collaboration Edition leverage new Web service components to provide integration between best-of-breed collaboration tools of IBM Lotus Quickr and IBM's ECM repositories.
The new release is available today.

My comments:
  1. These bundles have been well-received by customers looking for integrated collaboration and document-management solutions.  
  2. Typically, larger enterprises already have document-management infrastructure, whereas these bundles are intended for those that do not have the back-end in place.  They typically score well in the mid-range organisations.
  3. Both FileNet and Content Manager are considered best-of-breed by analysts, and tend to do well in competitive situations.  They have their own strengths and weaknesses, which sometimes leads to confusion in terms of which is the right solution for a given situation.
  4. FileNet Content Manager P8 5.0 is a big step forward, with CMIS support, Content Federation Services (enables federated content to be moved from source repositories into P8 native storage) and more.
  5. Lotus Quickr 8.5 is probably the most significant upgrade in the history of the Quickr/Quickplace product line.  It has received great feedback in every upgrade we've completed for customers.


 
 

Entire movies compressed into single barcodes

07 Mar

The Matrix compressed

Choice of color in a movie can say a lot about what's going on in a scene. It sets the mood, changes the tone, indicates a change in point of view, so on and so forth, which is why moviebarcode is so fun to click through. The concept is simple. Take every frame in a movie and compress it into a sliver, and put them next to each other. Voilá. Movie barcode.

The above is The Matrix, making it obvious when they're in and out of the system. Below are Kill Bill and The Social Network, respectively.

See dozens more on the moviebarcode tumblr, which is also selling these as prints.

Introducing the Google APIs Explorer

07 Mar

Google is always looking for new ways to make it easier for developers to get started with our APIs. When you come across a new Google API, you often want to try it out without investing too much time. With that in mind, we are happy to announce the Google APIs Explorer, an interactive tool that lets you easily try out Google APIs right from your browser. Today, the Explorer supports over a half dozen APIs – and we expect that number to grow rapidly over the coming weeks and months.


By selecting an API you want to explore, you can see all the available methods and parameters along with inline documentation. Just fill out the parameters for the method you want to try and click “Execute”. The Explorer composes the request, executes it, and displays the response in real time. For some APIs that access private data you will need to “Switch to Private Access” and authorize the Explorer to do so.

To get you started, here are some sample requests; follow the links and press “Execute”:

The Explorer makes it easier for developers to discover what APIs we offer and get started using them within minutes. If you have any questions or comments, visit the help page or the support forum. We’d love to hear your feedback.

Happy exploring!

Well-being of the nation mapped

Well-being of nation

Analyzing Facebook and Twitter updates to gauge happiness is all the rage these days, but Gallup has been doing it old school for the past three years. Every day, Gallup has called 1,000 randomly selected American adults and asked them a series of questions about their well-being such as, "Did you experience feelings of happiness during a lot of the day yesterday?" and "Do you smoke?"

Matthew Bloch and Bill Marsh for the New York Times mapped the responses for the past calendar year. Use the browser to quickly compare well-being in your area and across the country.

Above is the composite index of all the indicators. Looks like there's some good stuff going up north. Maybe not so much in the southeast.

The interactive is most interesting when you start comparing areas (especially near your own) and indicators. For example, here's the map for percentage who exercise:

Now with almost a complete flip, here's the map for smoking:

Find anything interesting? Let's hear it in the comments.
