urm,using best unifi with tunnel i think u can get around 180-200ms
using normal broadband will get u u 220-2xx ms since broadband is not very stable and depends on your  speed.
if you worried about pvping and the latency issues..most of the guys here are from aussie and they have around the same latency as ours,thats y we are the worst battlegroup on blizzard,
pve wont bother u that much..

First gate = Kill the Stonegazers and the Wastewalkers first.
2nd Gate =  Kill the Venom Priests and Effusions first. Interrupt as much possible.
3rd Gate = Kill Frozen Warlord first
4th Gate = Kill Shamans and Flamecasters first. Tanks tanking warbears must face them away from raid to avoid cleaving.

Interrupt immediately Dinomancers and kill them on each gate. The faster you bring him to 50% hp, the faster he drops the orb to MC Horidon to destroy gates; otherwise the adds will keep coming.
       
The other adds you just slowly cleave down, no rush. If you can do the above, you're almost guaranteed to get a kill. Just make sure dpsers don't tunnel on boss and forget the above adds.

In phase 2, save your cooldowns and Lust for the Warlord Jalak. Kill him ASAP, then Horidon.

Good luck on your kill.
