With the -n added to the option it won't resolve IPs so it
shouldn't take that long, but otherwise:
cat /proc/net/sockstat
sockets: used 284
TCP: inuse 16 orphan 0 tw 0 alloc 18 mem 1
UDP: inuse 12
RAW: inuse 1
FRAG: inuse 0 memory 0
I believe the tw is the time_wait count, just:
awk '/TCP:/ {print $7}' /proc/net/sockstat
