I’ve given access to iviewer to some pathologists that I’m working with and came back with some feedback about browsing speed.
One issue in particular is that since the image is fetched tile-wise, jumping between regions of the image can appear pretty slow. At the moment it takes between 600-1000 ms to load tiles when the viewport is changed (measured in the network monitor of Chrome). When using OpenSeaDragon it is possible to ask the tool to pre-load all tiles, even if the tiles aren’t actually drawn until the viewport is moved. Is there such an option in iviewer?
Are there any other options in Omero Server/Web that can be tweaked to improve image loading speed in the browser?
