Upgrading Your High Speed Internet
I just upgraded my internet from 6 Mbps (Comcast's standard cable speed) to a 16-Mbps service. Then, I logged in to Vanguard -- what a massive difference! Even running around Khal is smooth as silk now.
This should go a long way to resolving raid lag issues.
My point is, check in your area if such an upgrade is available. It's definitely worth it!
