Greater performance can be expected with caching enabled (default) and using 8+ core machines. Greater libvips performance can be expected with caching enabled (default)
and using 8+ core machines, especially those with larger L1/L2 CPU caches.
The I/O limits of the relevant (de)compression library will generally determine maximum throughput. The I/O limits of the relevant (de)compression library will generally determine maximum throughput.
