A post on Lemmy@lemmy.ml took over 4 hours to deliver. The comments haven’t made it in 7+ hours.

I see no evidence that the load is that high, what I see is failing on moderate message and post load, as in 3 to 4 out of 10 of what ‘busy’ would be like. There really are not that many new postings and comments, the comment counts are pretty low across several communities.
