max_cache_size recommended value?
Using:
Code:
import vapoursynth as vs core = vs.core clip = core.std.BlankClip() clip = core.text.Text(clip, str(core)) clip = core.std.Trim(clip=clip, first=0, last=1) clip.set_output() Quote:
Having 64GB RAM, I was wondering when it would make sense to increasing/decreasing this value. Is there a recommended value for max_cache_size? Has anyone done some testing whether/when increasing/decreasing makes sense? Cu Selur |

If you process very high resolution things it can make sense. Note that if the cache ever becomes full you'll get a warning.
Unlike avisynth that always caches up to the max limit vapoursynth will shrink/grow caches based on what's optimal for the current request pattern. That means you can check the ram usage in task manager or similar and see if increasing would do anything at all. 4GB is enough for just about all fullhd script and probably a significant number of 4k ones.
