efficency of jni method call?

hello!

i am new with jni, and my english is poor also, hope somebody know what i have said.

recently, i am developing a gis application with jni, the spatial data is processed with c++, i use java to get data and draw shapes by calling jni methods, but i find it's very slow when drawing. by the way, i fetch data of every shape dynamicly by calling jni methods when drawing. so i want to know if it is inefficient when calling jni methods so frequently, especially in huge loop?

thanks!
