// Profiling of a 1000 image load on quad core, single 80+MB/s capable SSD shows the following:
// - one thread: 100% normalized execution time, 35% CPU, 16MB/s disk (100% normalized time = 1 minute 58 seconds)
// - two threads: 55% normalized execution time, 50% CPU, 17MB/s disk (6.3% normalized time with dark checking skipped)
// - three threads: 46% normalized execution time, 70% CPU, 20MB/s disk
// This suggests memory bound operation due to image quality calculation. The overhead of displaying preview images is fairly low;
// normalized time is about 5% with both dark checking and previewing skipped.
//
// For now, try to get at least two threads as that captures most of the benefit from parallel operation. Video loading may be more CPU bound
// due to initial frame rendering and benefit from additional threads. This requires further investigation. It may also be desirable to reduce
// the pixel stride in image quality calculation, which would increase CPU load.
//
// With dark calculations disabled:
// The bottleneck's the SQL insert though using more than four threads (or possibly more threads than the number of physical processors as the
// test machine was quad core) results in slow progress on the first 20 files or so, making the optimum number of loading threads complex as it
// depends on amortizing startup lag across faster progress on the remaining import. As this is comparatively minor relative to SQL (at least
// for O(10,000) files for now just default to four threads in the disabled case.
//
// Note: the UI thread is free during loading. So if loading's going slow the user can switch off dark checking asynchronously to speed up
// loading.
//
// A sequential partitioner is used as this keeps the preview images displayed to the user in pretty much the same order as they're named,
// which is less confusing than TPL's default partitioning where the displayed image jumps back and forth through the image set. Pulling files
// nearly sequentially may also offer some minor disk performance benefit.
