> For the 0.14 release testing, I tried out the [MNIST LeNet example | https://github.com/apache/incubator-systemml/blob/master/scripts/nn/examples/mnist_lenet-train.dml] on both 0.13 and 0.14 and noticed a possible regression.  Basically, on 0.14 the script took longer to run and had 2513 Spark instructions executed, while on 0.13 only 864 Spark instructions were executed.  This was run locally on a laptop using the 2 instructions at the top of the script (and copied below).  I've also attached the stats and runtime explain logs.
