	cat /proc/slabinfo | grep nf_conntrack
or 'slabtop' can show the object size used by conntracks.
It should be 240+ bytes. You can expect one conntrack per
IPVS connection. You can also see conntracks with
cat /proc/net/nf_conntrack | less

	cat /proc/sys/net/netfilter/nf_conntrack_count shows
the current number of conntracks. You can look for 'count'
at __nf_conntrack_alloc() and nf_conntrack_free() to see
how it is implemented.
