The world is extremely diverse. You are in a group of lucky/happy users but I’m not there as I regularly unzip hundreds and hundreds generated files we are using in our project — they immediately making the Syncthing stuck for hour or two.
For me it’s terrible situation as it blocks syncs when you need to get them fast. If the app which main function is to “sync files” can’t do that efficiently because they are small — it’s unacceptable for me. Somehow borg, git, resilio are working with them fine but for Syncthing this is unliftable task. I’m not alone here as Syncthing’s forum regularly gets this topic up. Also I don’t want to work around this somehow as I don’t need another one workaround in my daily routines.
PS: it’s my personal opinion/case and I cannot blame somehow authors of the free and open source tool that they didn’t design it as I would expect — I just use another sync tool which works fine.
I've been using Syncthing for years to keep thousands of files in sync and it's been working wonderfully.
