What is a reasonable value for upstream zone size? I'm just shooting in the
dark with 64k right now. Running 64bit Linux. The official NGINX
documentation does not elaborate on it, and I can't find anything useful on

upstream backends {
    zone example_zone 64k;
    keepalive 8l;

    server max_fails=3 fail_timeout=30s;
