Hi, a couple of questions about ejabberd settings.
1. For OpenSRF, is the "localhost" entry required in the hosts directive?
{hosts, ["localhost", "private.localhost", "public.localhost"]}
Or can it be safely omitted with just the private.localhost and
public.localhost hosts listed?
2. Max_stanza_size.
Ejabberd documentation says:
{max_stanza_size, Size}
This option specifies an approximate maximum size in bytes of XML stanzas.
Approximate, because it is calculated with the precision of one block of read
data. For example {max_stanza_size, 65536}. The default value is infinity.
Recommended values are 65536 for c2s connections and 131072 for s2s
connections. s2s max stanza size must always much higher than c2s limit. Change
this value with extreme care as it can cause unwanted disconnect if set too
low.
OpenSRF instructions say:
Change all max_stanza_size values to 2000000.
The OpenSRF-recommended value is the same for c2s and s2s connections, which
differs from what the ejabber documentation suggests. I am curious about a)
what requires these values to change for OpenSRF in the first place, b) why the
OpenSRF-recommended value for c2s and s2s is the same, and 3) why a power of 2
is not used for it, e.g., 2097152?
Any "science" behind these and other OpenSRF-recommended settings, or just safe
guesses?
Thanks.
