Why testing is very slow #7

Open zyzhong opened 8 years ago

Training is very fast, why testing is so slow? It seems the whole testing procedure is single thread, but why the console output "using up to 12 threads" during testing?

Can you elaborate on how slow it is, and show me an example? The testing is multithread but the parallelization is over the trees, not over the examples (which may not be the most efficient implementation).
