Rails, Unicorn, Concurrent Requests Breaks app -


i have ruby on rails app deployed , ran bottlenecking issue when many users tried use it. it's simple game stats application. user enters name, app makes api call, , returns user's stats. works when there few users. when more users started using though, creates insufferable lag, of 5 minutes per request. therefore, added unicorn gemfile, set procfile, , deployed it. now, if there 2 simultaneous requests, crashes app. thought unicorn meant handle concurrent requests, not destroy them? @ least before, requests still processing, albeit delay. doing wrong here?

here procfile used:

web: bundle exec unicorn -p $port -c ./config/unicorn.rb 

here unicorn file:

worker_processes 3 timeout 30 preload_app true  before_fork |server, worker|    signal.trap 'term'     puts 'unicorn master intercepting term , sending myself quit     instead'     process.kill 'quit', process.pid   end    defined?(activerecord::base) ,     activerecord::base.connection.disconnect! end  after_fork |server, worker|    signal.trap 'term'     puts 'unicorn worker intercepting term , doing nothing. wait     master sent quit'   end    defined?(activerecord::base) ,     activerecord::base.establish_connection end
