if you redownload, it might be a bit faster. i am caching internal structures now and skip checking for existense of the MLV file internally.
Nice

you are on a good direction!
Plain copy mlvfs CPU usage: (tested on my home pc which is more powerful (1ghz diff) hence smaller numbers than in previous posts)
25feb build - average ~7-8%, peak ~18%
27feb build - average ~4-4.5% peak ~15%
Throughput about the same ~115mb/sec
Results are collected from 10 runs each, hence no placebo

In resolve 27feb build definitely snappier! almost no lug on play/pause/rewind/fast forward/scrub, however, not very-very-very sure 'bout it, could be a lil'bit placebo effect
