The Apache Benchmark (ab) tool is a simple way to do rough benchmarks of a site's speed

ab -k -n 10000 -c 200 https://www.example.com/

Meaning of this code

• "-n" number of requests
• "-c" number of simultaneous connections
• "-k" keep alive time

Optionally you will want to pass other headers

• e.g. " -H "Accept-Encoding: gzip, deflate" since this is common and takes a toll on performance

You'll get some results.

E.g. I had serious issues (2/3 of requests dropped) at this level

Complete requests:      10000
Failed requests:        6718
Time per request:       3363.407 [ms] (mean)
Connection Times (ms)
              min  mean[+/-sd] median   max
Connect:      327  443 250.9    386    4684
Processing:   195 2864 2551.9   2414   24075
Waiting:      127 2747 2552.6   2288   23958
Total:        586 3307 2660.2   2824   25621

Check if the response times (means, min/max, failed requests) are acceptable for your use case.
