Hi Mac People

I have a question I'm hoping someone with some tech know how might be able to help me with. I'm playing on a relatively new iMac. The game runs but I have a couple questions.

It takes almost 5 1/2 minutes from the time I click the DDO short-cut to being able to move my character in game. Switching instances is a crapp shoot I frequently lose. Some times, it's quick (and by quick, I mean, I load the instance at the same time as the rest of the party) but most times it's painfully slow (rest of party is well into the next instance/quest - 1-2 minutes for my instance to load). And finally, the freezes mid-game are frequent and last 4-5 seconds at a time. I don't think this is the game-lag people complain about - if I'm ahead of people and sprint boosted, then freeze, the group will be ahead of me. I'm assuming this is just me?

So my question ... is this just the price of gaming on an iMac? Is it because I'm playing on a Wifi connection with 2 teenage girls and multiple Wifi connected Tvs in the house?

And most importantly, is there anything practical I can do?

My gaming experience is getting painful. Playing harder content on a caster .. freezes are bad bad bad.

Thanks for any help (ideally in small words, I am painfully not tech savvy).
