It is observed in a local 8 drive system the CPU seems to be
bottlenecked at

Bonus changes:

- re-use transport for bucket replication clients, also site replication clients.
- use 32KiB buffer for all read and writes at transport layer seems to help
  TLS read connections.
- Do not have 'MaxConnsPerHost' this is problematic to be used with net/http
  connection pooling 'MaxIdleConnsPerHost' is enough.
