I’m trying to stress a website. For that I’m using one AWS instance (8 CPU, 30 GB memory, Linux). We want to reach 200000 reqs/sec, but only get ~4800.
I followed https://gatling.io/docs/2.3/general/operations/ but the limit seems to be in 4800 reqs/sec. When I try to increase that number returns “Failed to open a socket”.
How can increase concurrency?
