Besides what all have suggested, can you share your testing setup? Are you using JMeter? I'm asking this to confirm that your setup is "actually trying" to generate 1000 simultaneous threads and not bottlenecking the process. I get 170 qps easily on a simpler server but I remember that I could not go past 200 threads due to my testing PC limitations (I was firing queries from my PC to the server).
