如何优化munin fw_conntrack脚本

我有一个在ip_conntrack约65k连接的服务器。 我如何优化munin脚本来计算各种types的连接（默认fw_conntrack脚本）：

 cat /proc/net/ip_conntrack | awk ' BEGIN { STATE["ESTABLISHED"]=STATE["FIN_WAIT"]=STATE["TIME_WAIT"]=0; TOTAL=ASSURED=NOREPLY=STATE["SYN_SENT"]=STATE["UDP"]=0; } /^tcp/ { STATE[$4]++; } /^udp/ { STATE["UDP"]++; } /ASSURED/ { ASSURED++; } { TOTAL++; } END { print "established.value " STATE["ESTABLISHED"]; print "fin_wait.value " STATE["FIN_WAIT"]; print "time_wait.value " STATE["TIME_WAIT"]; print "syn_sent.value " STATE["SYN_SENT"]; print "udp.value " STATE["UDP"]; print "assured.value " ASSURED; print "total.value " TOTAL; }' 

目前大约需要30秒才能执行。
