The
scache(8) connection cache server logs statistics about the
peak cache size and the cache hit rates. This information is logged
every
connection_cache_status_update_time seconds, when the process
terminates after the maximal idle time is exceeded, or when Postfix
is reloaded.
-
Hit rates for connection cache lookups by domain will tell
you how useful connection caching is.
-
Connection cache lookups by network address will always
fail, unless you're sending mail to different domains that share
the same MX hosts.
-
No statistics are logged when no attempts are made to
access the connection cache.
