my latency from Johor TMnet's streamyx is 250ms for both stable. Spike is very seldom since beginning of this year.

No tunnel.

No torrents usually, if torrent i limit it to very low ups and down.

Are you using stock unifi router? I guess that is probably true. - I cant recommend you a better router... but my experience is stock crappy TMnet provided equipment is crap.

Try on different equipment. Try do your http://www.speedtest.net/
connect to server in US. See if it is a problem with equipment.

Could be worth a try as I know that there are quite a number of people who play wow without tunnel now and can get 250 +/- latency.

If you want to get a recommendation for better unifi equipment, try check out the broadband threads.
