I subscribed to communities, but my Lemmy instance receives only a few posts, comments and votes. I can see linked instances, but whether or not they sync data feels hit or miss. I’m not quite sure if this is expected. Does Lemmy have a utility similar to the Matrix federation tester?
I’m seeing lemmy.ml communities that aren’t replicating posts and comments properly to other major instances.
Everyone keeps upgrading the hardware, but the PostgreSQL database seems to have a lot of locking issues / concurrency contention with federation and user activity at the same time.
Example: this posting over on Beehaw is currently lacking the comments: https://beehaw.org/post/536574
Another site, it is there, but only 2 of the 4 current comments: https://sh.itjust.works/post/74015
