Hi Gunther,
I am trying to get the most performance out of my system. I am processing up to 2000 42MP raw images in LR to produce LRT video output. I would like to run multiples of these at once, but my processor is maxed out. I remember being told that these programs (LR and LRT) are only single threaded and yet my measurements indicate otherwise. I have an Intel I7 4770 @3.4MHz with 4 cores and 8 logical processors. If I run a single export from LR to LRT, all 8 logical processors run at around 75% busy. Also, if I observe how LRT is exporting I see that the count goes - 1.2.3................4.5.6...................7.8.9.................10.11.12... - etc. This would indicate to me that LR/LRT is processing 3 images at a time and that each image is possibly multi threaded. This implies that if I use an identical processor with 8 instead of 4 cores, I should significantly improve the performance, particularly if I run multiple exports at once. Currently if I do two exports then I gain nothing as the CPUs still run at about 75% busy (probably IO limited). I run solid state disks for all major IO.
