Re: Microsoft seeks naive and ignorant Linux user
"Even with Oracle database products, Microsoft ensures that it cannot perform on Windows as it does on Linux"
That's historically got a lot more to do with Oracle's use of crapware like Java, Oracle's poor adoption of threading and users not implementing Oracle recommended settings than anything deliberate by Microsoft. From Windows Server 2008 and Oracle 11g R2 onwards these issues are largely fixed provided you follow the Oracle recommendations - and you now get similar performance on Windows Server versus Linux for the same hardware.
"superiority of database systems like PostgreSQL "
PostgreSQL has had more security holes, has far fewer features, and has way lower benchmark performance - so not quite sure how that's superior?
