Performance Guide

In this section we’ll go into a bit more detail about how to get the most out of FFCV.

In Working with Image Data in FFCV, we give more details on working with image data, including how to fine-tune to your specific resource requirements.

In the Tuning Guide, we give recommendations on how to optimize your system for a couple of common use cases.

In The Bottleneck Doctor, we distill the concepts from the tuning guide into a general map from the scarcest system resources to FFCV options.
