J/Link speed of accessing arrays

I'm trying to use Mathematica as an interactive front end to for a set
of java objects using J/Link.

My question is this: what is the fastest way to access a given attribute
for each element in a large java array. For a 1000+ element array the
process is painfully slow using code like this on Windows NT:

myArray = myJavaClass@getArray[];
sum = 0;
Do[sum+=(myArray[[i]])@getAttribute[],{i,Length[myArray]}];
Print[sum]
