HANA service performance: calculate, return and insert - Fastest approach?

Hi,

Let's assume the scenario:

1. An external HTTP client calls HANA service
2. The service calculates the result of a formula
3. The result is returned to the caller
4. The result is stored in the database.

The above happens 1000 times in a second.

I am a beginner, but I would create a XSJS service, for example getResult.xsjs, with function which calculates result and sets response, and another one in jQuery.ajax call with asynchronous "INSERT INTO" (would this improve client's performance?).

Is this correct in the first place, and if yes, is this the best (the fastest) approach? Are there any documents/success stories/benchmarks which would compare HANA's performance with some other technology?

Thanks!

KR,
