When trying to save an InDesign document with the Xinet Metadata ID plugin Adobe InDesign for MacOS, users are experiencing long save times when saving an InDesign document with the plugins enabled. Users report that it takes 10-18 minutes on huge files with many linked images and pages.
Writing of metadata to these large files is expected to produce these longer load times. A Product Enhancement has been submitted to provide an improvement on the performance of the plugin in future releases.
As a workaround, you can utilize the following macOS commands to reduce the Preview Sizes and Generate Previews only for thumbnails, which can provide some improvements:
# defaults write com.xinet.indesign.webnative MaxPreviewSize -int 600
# defaults write com.xinet.indesign.webnative WhichPreviews -int 1
|0||Disable all Previews|
|1||Thumbnail Previews Only|
|2||Enable Full Previews|
