Clients connect using TCP. The request from clients are now stored in files for processing, that is why I said 100-200 files/sec. This is currently the fasted rate at which request can be stored. This I would like to improve by using a database with INSERTS, which is considerably faster. But to process these queued requests (either in files or database), the filesystem is much faster again. So I need to find the best of both worlds, actually.
