My colleague Martin Ridgway recently posted on how your web site’s performance is important to the user experience. Of course this is true for WebSphere Portal sites as well, so I wanted to steal…er, leverage his recommendations and elaborate with some specifics on how we see those implemented within WebSphere Portal sites. Before I go […]

Your website’s performance is part of its user experience too
Creating a great user experience extends beyond the research, beyond the wireframes, and even beyond the visual design. All that hard work is ultimately for nothing if your website or web application isn’t fast. Why? Because if your site doesn’t load quickly, your users will go elsewhere very quickly indeed!
Reengineering the Forecasting Process with Predictive Models
Reengineering the Forecasting Process with Predictive Models Forecasts usually start as historical performance which is then reviewed and adjusted based upon anticipated events. More mature forecasting may also incorporate generally accepted business rules “programmed in” to help “drive” the data into a forecast. Over the years I’ve deployed uncountable applications which provide the ability to […]
Using Grouping and Cursor to improve performance
Summary: In BI testing, we create views for large amounts of data, but performance issues can occur when we need to pivot a column and make it a string. To improve the performance, we divide this column into two groups first, one is for the unique value that doesn’t need any combination, and another one […]
Using Splunk for WebSphere Application Server
Splunk hosted a webinar earlier today on their Splunk for WebSphere Application Server 2.0 application. This is an application they wrote that extends Splunk’s already powerful capabilities to provide WebSphere-specific searches and reports. If you’re not familiar with Splunk, you should take a look. In a nutshell: Your IT infrastructure generates massive amounts of data. […]
Digital Dashboards and Stone Cairns
Guideposts An intelligent, data driven digital dashboard might be described as a corporate guidepost providing insight for an ongoing journey towards profitability. An interesting comparison might be found in the form of ancient store cairns found throughout many countries including Scotland, Ireland, Tibet, and the Arctic. These sculptures were often created as directional markers pointing […]
Managing BI Performance Problems Series Part 2: Indexing
When it comes to performance problems indexing is the bread and butter of most data warehouse developers. And why not? It’s a cheap and easy way address simple performance problems. However, like anything cheap and easy it can only fix the cheap and easy problems. Indexing will not solve large underlying performance problems, but it […]
Liferay 6 Performance
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 […]
WebSphere Portal v7 Tuning Guide just released
If you don’t regularly check the IBM Portal wiki or subscribe to updates via RSS, you might not have seen the WebSphere Portal v7 Tuning Guide that was just released. Many of the sections are similar to the previous editions, but there are also new sections for areas such as: Disabling features you might not […]
Using SSL only for some WebSphere Portal pages
A nice article was recently published on IBM’s WebSphere Portal wiki about using a mixture of HTTP and HTTPS pages on a WebSphere Portal site. The reasoning for that approach is basically that you need to encrypt certain sensitive traffic, but don’t want to encrypt traffic for the entire site for performance reasons. Before you […]
