Andrea, thank you so much for your tests. Probably, your computer's performance is so high that you can't see this latency I can see. In my laptop, switching "Charlie" governor from Powersave to Performance, it is more responsive but not much. My Laptop has 8GB of RAM. Once the Project is loaded into Cinelerra-GG, Top program says: - for Cin program: %MEM=26.1 (max peak 38) - Total Mem Used: 2500000 KiB (of 8GB) This , using "Use thumbnails in resource window" = CHECKED in Settings-> Preferences.

When/if you have time,... I add a compressed file where you find my Project.
I tried out your project, but I don't notice any slowdowns.
How much RAM do you have? How did previous projects with multiple media files and clips perform?
