   @szha Can we turn on the USE_LIBJPEG_TURBO flag. I find that it helps improve the speed of IO pipeline significantly?
   
   Results for Resnet50 v1 Imagenet, 480px resized data, batch size 1920, float16, symbolic:
   Current: 3600samples/sec
   With libjpeg-turbo: 4600samples/sec
   
   As an example, Here's how I used LIBJPEG_TURBO on ubuntu.
   ```
   sudo apt-get install autoconf automake libtool nasm
   JPEG_TURBO_VERSION=1.5.2 && \
   wget -q -O - https://github.com/libjpeg-turbo/libjpeg-turbo/archive/${JPEG_TURBO_VERSION}.tar.gz | tar -xzf - && \
   cd libjpeg-turbo-${JPEG_TURBO_VERSION} && \
   autoreconf -fiv && \
   ./configure --enable-shared --prefix=/usr 2>&1 >/dev/null && \
   sudo make -j"$(nproc)" install 2>&1 >/dev/null && \
   rm -rf libjpeg-turbo-${JPEG_TURBO_VERSION}
   ```
   Flags
   `USE_LIBJPEG_TURBO=1 USE_LIBJPEG_TURBO_PATH=/usr`
