Performance parameters for apache atlas

New Contributor

How to configure apache atlas handle 500 api request at same time, to achieve this concurrency I tried increasing the performance config parameter: 

atlas.graph.storage.lock.retries=10
 atlas.graph.storage.cache.db-cache-time=120000 
 atlas.webserver.minthreads=10
# changed below param to 300
 atlas.webserver.maxthreads=100 
 atlas.webserver.keepalivetimesecs=60 
#changed below param to 150
atlas.webserver.queuesize=100 

but somehow if number of concurrent api requests goes to 300, around 48 request get failed.
I have given cpu as 32 core and memory as 16 Gb.
