...20-40 requests per second from users, and each of these requests will make 10-30 requests to some db..
200-1200 for now, and will grow even more in nearest future.

Sure, mysql is a good thing. But it just can't resolve my situation (tested already).

Why to keep data in DB/files if it's stand alone application? The question for which I'm seeking answer is "how to get this data from application and store to disk/db/other memory".

Thanks anyway. Got know some new information after reading :)
