We've been experincing very long upload times on our assemblies and drawings. Typical upload times are a few seconds, but we've seen it as high as an hour on large assemblies. It's not uncommon for a simple 6 component assembly to take 10-15 minutes to upload. In trying to diagnose this, I found that the file size is huge when upload takes so long. The increase ranges from 10x to 20x. I cannot for the life of me understand how the file size could change so dramatically. After this discovery, we tried check-in w/o any config files. It behaved as expected, with a short upload time. Then we re-introduced the normal configs, and again it worked as expected. I was not able to reproduce the long check-in time and file size growth. Has anyone else seen this?This thread is inactive and closed by the PTC Community Management Team.
