Settings for poor hardware

[Purfview]

beam_size=1: can speed-up transcription twice. [ small impact on accuracy ]

compute_type: test different types to find fastest for your hardware. [--verbose=true to see all supported types, use -fallback=None when doing benchmarks for comparison]

To reduce memory usage try to reduce incrementally: --best_of=1, then --beam_size=1, then -fallback=None.
