title: XGBoost training time seems to be too long
body: <p>I am trying to train an XGBoost classifier in Python using the xgboost package. I am using the defaults on all the parameters for the classifier and my training set has around 16,000 elements and 180,000 features for each element. I am not using the gpu to train the model, but still, the training process has taken more than five hours and is still going. I have 32GB of RAM and a 6 core Intel I7. I am wondering if this is normal time for training this classifier with the amount of data I have because I have heard of people training the model in a couple of minutes.</p>
