What is the best way to get the max request / sec in benchmarks?

[rodrigoslayertech]

Hello!
I want to know the best practices to get the max request by sec in benchmark tests.

1. I need to execute the test in the same host of my drogon server instance or in another host to not to steal cpu resources?

2. Running test on localhost can I have the highest request by sec possible or is it better to run on a separate physical machine with a network cable connected in direct connection (without using VMs of course)?

3. Whats is the fastest HTTP benchmarking tool? I'm using wrk.

I'm running the tests in a VirtualBox virtual machine on my Windows running Debian and I can get a maximum of 80k/sec

My Drogon config:
app().setLogPath("./");
app().setLogLevel(trantor::Logger::kWarn);
app().addListener("0.0.0.0", 80);
app().setThreadNum(16);
app().enableRunAsDaemon();

My Benchmark command:
wrk -t12 -c400 -d10s http://localhost

My VM in VirtualBox:
Debian 11
4 CPUs
4 GB RAM
Guest additions installed

My Physical CPU:
AMD Ryzen 9 3900X 12Cores / 24

My Video card:
NVIDIA GeForce 2070S
