title: optimal size of a tfrecord file
body: <p>From your experience, what would be an ideal size of a .tfrecord file that would work best across a wide variety of devices (hard-disk, ssd, nvme) and storage locations (local machine, hpc cluster with network mounts) ?</p>
  
  <p>In case I get slower performance on a technically more powerful computer in the cloud than on my local PC, could the size of the tfrecord dataset be the root cause of the bottleneck ?</p>
  
  <p>Thanks</p>
