Default monerod configuration speedup
Why are the default monerod configurations very low?
Download is limited to 8 MiB/s, upload is limited to 2 MiB/s, and the maximum number of peers to download from (in) is limited to 12.

Could we increase the default limits to 1024 MiB/s download, 1024 MiB/s upload, 512 in_peers, and 512 out_peers?
Torrenting software typically don't have artificial transfer speed limits and they manage fine. We should too.

./monerod --help shows
```
  --out-peers arg (=-1)                 set max number of out peers
  --in-peers arg (=-1)                  set max number of in peers
  --tos-flag arg (=-1)                  set TOS flag
  --limit-rate-up arg (=2048)           set limit-rate-up [kB/s]
  --limit-rate-down arg (=8192)         set limit-rate-down [kB/s]
  --limit-rate arg (=-1)                set limit-rate [kB/s]
```

These limits are all what is by default, except the `--out-peers arg (=-1)`, which is actually 12. Maybe this was changed, or perhaps 12 is a fallback value from an incorrect configuration. If you pass `-1` as any of the arguments, it doesn't set it to unlimited but retains the default (which may be a fallback).

Maybe you would also want to increase the default maximum number of connections per ip from 1 to 32 or remove the restriction completely, as this impacts users with shared ips (same network, large business, VPN, cloud provider) when there are a large number of monero users on the same network.
