Hi, i’m using osimis viewer to view study from orthanc. I find out the speed of loading the first image is slow for first time viewing the study especially large study like CT scan. But after second time we open the study using osimis viewer, the loading of first image is fast, maybe because of it already have previous cache.
Is there any method that we can implement to make the first viewing using osimis viewer better?
Thank you in advance,
Regards

Hello,
I would advise to use the Stone viewer (https://book.orthanc-server.com/plugins/stone-webviewer.html) in place of the Osimis viewer (which is deprecated). From the last version, all the Osimis viewer features are available in Stone 
If you use the osimis docker images, it is already embedded and you can enable it through the env vars.
The speed you observe is probably due to the DB access rather than the images loading, so if you switch to Stone, it should be faster… especially if you set the extra main dicom tags according to: https://book.orthanc-server.com/faq/main-dicom-tags.html?highlight=dicomweb#adding-more-tags-in-db
HTH,
