Hello Oxiel,
first of all I'm going against my interests: sql server has really great
performance on low profile hardware such as intel.
But a choice of the right platform shouldn't be based on performance.

To be back on your question: how to boost performance of oracle on linux?
There are a couple of Scalzo's papers on the topic. They are old but you can
still find useful tips.
Then you can try changing the default I/O scheduler. Benefits of this
approach depends on your workload so test carefully!!!!

Still I suggest you to prepare a broader number of justifications if you
want to chose a solution above aqnother.
Things like: stability, backup and recovery scenarios, internal
administration skill of your organization, development advantages of the two
solutions and so on.

Regards
Fabrizio
