Benchmark wanted: copy throughput

[ry]

outlined here: #884 (comment)

Should wait for #884 to land.

In the future we will want to compare it to TLS throughput.

It makes sense to also compare it to a program that measures stdio throughput:

// time head -c 100000000 /dev/zero | deno this_script.js
import * as deno from "deno";
deno.copy(deno.stdout, deno.stdin);

What counterpart should it compare with? Golang? You need to set a performance goal such as "it should be similar to Golang". Then we need to port all benchmarks to (for instance) Golang so that we get relative numbers and not just "1 million unnamed units of performance". You want to get numbers like "0.79x of Golang".

No counterpart needed for the first version - would like to just get continuous look at the perf

I can't get any of the examples to work on Windows or Linux. Deno just exits as soon as there's a connection. I downloaded the 0.1.7 binaries.

This is what I ran:

import * as deno from "deno";
let listener = deno.listen("tcp", "127.0.0.1:4500");
listener.accept().then(async (conn) => {
  await deno.copy(conn, conn);
  conn.close();
  listener.close();
});

Likely you are experiencing #919
We’ll have a new release in a day or two
