This machine is dedicated as a tor-relay. Is it normal that the INPUT bytes count is much greater than the OUTPUT bytes or did I configure the iptables wrong?

iptables -L -v Chain INPUT (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 6 328 ACCEPT all -- lo any anywhere anywhere 38 2557 ACCEPT icmp -- any any anywhere anywhere 1135 68123 ACCEPT tcp -- any any anywhere anywhere tcp dpt:http 27432 6416K ACCEPT tcp -- any any anywhere anywhere tcp dpt:https 6274 479K ACCEPT tcp -- any any anywhere anywhere tcp dpt:ssh 93821 129M ACCEPT all -- any any anywhere anywhere ctstate RELATED,ESTABLISHED 1050 54292 DROP all -- any any anywhere anywhere

Chain OUTPUT (policy ACCEPT 70579 packets, 36M bytes) pkts bytes target prot opt in out source destination
