best timeout defaults

Hey guys,

 Just wondering what y'all would consider the best / optimal timeout
settings for varnish servers to contact they're backends. Considering that
both varnish servers and web servers are in the same datacenter.

So, what values do you like for these settings:

For the health probe:

 .timeout = 1s;
  .interval = 2s;
  .window = 10;
  .threshold = 8;

And for the backend hosts themselves:

    .connect_timeout = 5s;
    .first_byte_timeout = 10s;
    .between_bytes_timeout = 2s;

Oh and heck. While we're at it, is there a general rule of thumb/best
practice for this one?

   .max_connections = 800;

Enquiring minds want to know!

Thanks!

Tim
