Hey there. I am doing some performance tests with different frameworks.

I tested lotus in development mode and it was way to slow. Then I started it in production mode but it was blocking the concurrent requests, probably by a security middleware. I got “connection refused”.

Is there a config for preventing this connection refused feature?

TIA

@mjacobus I’m using Lotus since yesterday and I had the same behaviour trying to do some ‘tests’ with `puma` and `siege` and there is some gotchas:

- there is the option `--no-code-reloading` to have a faster development, but is a tradeoff.
- the `lotus server` command start `WEBrick` by default, using `puma` gem I have the server listening only on ipv6.
- According the man pages from the siege version the URL format must be `[protocol://] host.domain.xxx [:port] [/path/file]`. I’m not sure if accepts the ipv6 host format `[::1]`.
- To bind to an ipv4 socket I used the `--host 127.0.0.1` option of the `lotus server` command.

Best

Hey man, thanks! You did some deep digging there =)

So I tried testing with --no-code-reloading and it was much faster =)

However I think that should still be faster in production mode. Development env has always some weirdness going on.
