Archttp version 1.0.2 has been released, and retesting has

Hi, thanks for the PR. I've rerun the tests for `archttp` and it
is indeed much better.
Now on par with `vibe-d`
Some more notes for a better performance (it's the same with
`vibe-d` too).
See what syscalls are called during the request processing:
```
[pid 1453] read(10, "GET / HTTP/1.1\r\nHost: 192.168.12"...,
1024) = 117
[pid 1453] write(10, "HTTP/1.1 200 OK\r\nDate: Sat, 28 M"...,
173) = 173
[pid 1453] write(10, "Hello, World!", 13) = 13
```
It means two separate syscalls for header and body. This alone
have huge impact on the performance and if it can be avoided, it
would be much better.
Also read/write while working with a socket too, are a bit slower
than recv/send.
