We have dynamics offer system and have to make 10 requests / per user and get result in 2000ms. (concurrent user 1k)
I have tried parallel command, curl multi, java HttpURLConnection with thread and Apache connection management but couldn't work in 2000ms on dedicated server which have 32 core and 64gb RAM. My best stat is 130 concurrent user and average response time 4 seconds.
We're using php and java but we can't find right way for it. Have you any idea for right way?
Additional Information : I can reach 7k user with only 1 http request every user
