        Just like every connection, may be you can find
such message in dmesg/logs when IPVS starts:

        IP_VS_DBG(0, "Each connection entry needs %Zd bytes at least\n",
                sizeof(struct ip_vs_conn));

        You can also check 'slabtop' (cat /proc/slabinfo) on
load, look for ip_vs_conn. On my x86-32 platform it shows 240 bytes.
On x86-64 it should be more.
