Is Ubuntu Getting Slower? 544

Posted by CmdrTaco on Monday October 27, 2008 @08:31AM from the slow-like-a-fox dept.

An anonymous reader writes "Phoronix has a new article where they provide Ubuntu 7.04, 7.10, 8.04, and 8.10 benchmarks and had ran many tests. In that article, when using an Intel notebook they witness major slowdowns in different areas and ask the question, Is Ubuntu getting slower? From the article: 'A number of significant kernel changes had went on between these Ubuntu Linux releases including the Completely Fair Scheduler, the SLUB allocator, tickless kernel support, etc. We had also repeated many of these tests to confirm we were not experiencing a performance fluke or other issue (even though the Phoronix Test Suite carries out each test in a completely automated and repeatable fashion) but nothing had changed. Ubuntu 7.04 was certainly the Feisty Fawn for performance, but based upon these results perhaps it would be better to call Ubuntu 7.10 the Gooey Gibbon, 8.04 the Hungover Heron, and 8.10 the Idling Ibex.'"

Microsoft Woos Developers Under the Silverlight 300

Posted by ScuttleMonkey on Monday October 13, 2008 @04:15PM from the go-on-start-wooing dept.

CWmike writes to tell us that with the impending release of their Silverlight 2.0 product, Microsoft is poised to enact the next phase of their plan, wooing developers and designers directly. Microsoft is funding a French open-source project designed to allow programmers to utilize the Eclipse framework to build Silverlight apps. "Microsoft is also releasing for free a set of programming templates called the Silverlight Control Pack under its Microsoft Permissive License, as well as the technical specification for Silverlight's Extensible Application Markup Language (XAML) vocabulary via Microsoft's Open Specification Promise. The latter, said Goldfarb, should make it easier for would-be Silverlight developers."

Can you explain what exactly it is that makes it a lot harder? (And isn't a DBA paid to do his job?) Most real world business applications use partitionning in order to cope with very big tables. An auto-increment key is not a good candidate for splitting a table, as it will prevent spreading the data across the partitions for parallel processing, so you have to play with an application key (the auto-increment) and a partitionning key that the application has to set anyway when creating rows, which is far from optimal ... Anyway, good developpers understand the implication of what they do for the underlying database ... DBAs and DBMS won't fix your bad design decisions.
