5 years ago - The maximum setting with resource report is 1 million:
const maxRes = 1000000 - For more than 1 million requests, hey processes continue to execute in the back end, only statistically, those with more than 1 million status codes are not recorded:

When I ran performance with 2 mins or 5 mins duration, only 1,000,000 requests could be sent, Is it the maximum supported requests number? root@hey-client-http:~# hey -z 2m -c 1000 http://10.240.0.10 Summary: Total: 120.0524 secs Slowest: 1.1497 secs Fastest: 0.0007 secs Average: 0.1200 secs Requests/sec: 16104.9422
