When i start luring , and when comes more then some 8-10 mobs then they start laaging .
like they r gone soon.
And dont follow me very fast.
So need help .
My friend have this problem too.

If your own speed is set to 2, monster speed value should be set to 10.
Also try decreasing DwMoveDelay in your info.csv. Try 200, if you dc too much slowly increase it until you find a value that works for you.
