@jcupitt Thanks for getting back to me and for how responsive you are to the community. We are using Netvips to open and save using Image newImage = openslide.IccTransform("srgb", null, Enums.Intent.Perceptual, null, true); newImage.Dzsave(finalPath, uuid.ToString(), tileSize: tileSize, depth: Enums.ForeignDzDepth.One, suffix: QValue, skipBlanks: 1); The open and icctransform are very quick, tiling out a 2.8 GB svs file is taking ~3 minutes on k8s container running Ubuntu 20.04. Underlying nodes are 16 CPU with 32GB of RAM. How can I set the rgb value in using Netvips. |

It's just I'd try not setting What version of libvips are you using? I'd try building current stable and timing it. |

The ie. total CPU time drops from 65s to 53s. You'll see a smaller improvement in wall clock time, since with the greater load more of your CPU cores will fire up. You'll be able to run more dzsaves in parallel at least. |

We are using libvips/netvips to process whole slide images for digital pathology and we love it. We tile out our images using dzsave and then save to internal s3 storage.
We are trying to decrease the amount of time it takes to perform the dzsave operation. We are running on Ubuntu 20.04 on kubernetes with 16 cores. To tile out a WSI using dzsave for a 2.8 GB svs files its taking ~ 2 and a half minutes. Does anyone have any thought on steps that could be taken to reduce the amount of time to output the tiles using dzsave.
Thanks in advance
