Answer 1

what can I do to load the model faster?

Switch back to tf.train.Saver, as your question shows no motivations for using SavedModelBuilder, and makes it clear that elapsed time matters to you. Alternatively, an MCVE that reproduced the timing issue would allow others to collaborate with you on profiling, diagnosing, and fixing any perceived performance issue.
