I play from South Africa connecting to the EU servers. My latency is generally pretty non-impressive (around 700ms in general). About a month ago I added the TcpAckFrequency value to my registry, which improved my pings dramatically (running around 400-450 now regularly).
Recently, however, either as a result of the above change or probably totally unrelated, I've been getting latency spikes as soon as I enter a dungeon. Well, maybe "spikes" is not quite right - it's normally a case of the pings climbing steadily until they reach around 6,000-8,000, then I DC.
When I log back on (which happens pretty quickly, I might add), my pings just carry on climbing, starting from around 12,000. The worst I've had them was 18,000. I can't even type a message in party chat to my quite obviously peeved pug-mates telling them my problem, let along actually leave the party so they can get someone to replace me.
Eventually I'll disconnect again, and I'll stay off for a while, giving them time to kick me ... seriously, most of the time, that's the only way I can leave. When I leave the dungeon, the pings return to normal again after about 5 minutes.
So, the question is, WTF is going on here. If I do a ping /t to a mainstream website (www.google.com for example), the are consistantly in the 200-220ms range, all the time. Just before entering the dungeon, my wow pings are 400, and 5 mins after I leave, they're back there again, while I'm in the dungeon, they are sky-high.
Could the TcpAckFrequency change be causing this, or is there some other problem I could have a look at?
Thanks all in advance.
