Because netcdf WRF is staggered we take a very big memory and processing hit. 
We encourage users to run WRFPOST on their netcdf wrf files. This unstaggers 
the grid and also adds a number of commonly used fields.  

Doing things in 3D naturally causes memory and performance problems because we 
are dealing with the full volume of data. As the Performance Tuning web pages 
points out you can do a number of things -  
subsetting the times
decimation of the grid 
subsetting in space
caching the data to disk

I suggest you try some of these solutions before giving up on the IDV.
