I used a confidential dataset to benchmark the performence. 112 png files weighting 3.2 GB. The old import system took 75.96 seconds to import the data while blocking the gamethread. The Interchange system took 15.06 seconds to import the data whitout blocking the game thread, but my initial testing found that it resquested around 200 MB of memory then the old system. It's possible that this is due to the memory pool of each thread (it need investigation before jumping to that conclusion). Those test where made using a machine with a Xeon E5-2643 (6 cores/ 12 Threads) #rb Alexis.Matte #jira UEENT-3845 [CL 15164350 by Julien StJean in ue5-main branch]
