Avoiding unnecessary allocations
You should eliminate unnecessary allocations, especially when the size of an event is very large. For example:
event LargeEventWith1000Fields {}     // field definitions omitted
 
integer i := 0;
while (i < 1000) {
   route LargeEvent(0,0,i, ...);      // bad
   i := i + 1;
}
 
LargeEvent le := new LargeEvent();    // good
while (i < 1000) {
   le.foo := i;
   route le;
   i := i + 1;
}
