Updated & Pinned a Comment in this thread explaining my complete investigation and ideas on how the Lemmy app will & could move forward.
That’s sad.
I’ve seen you posted in the Lemmy Matrix channel, hopefully you’ll be able to find a way soon. I guess you already read the write-up from Db0? https://dbzer0.com/blog/post-mortem-the-massive-lemmy-world-lemmy-dbzer0-com-federation-delays/
Yes. Unfortunately the information gleamed boils down to two reasons:
Our db server is occasionally slow to respond, but most requests from LW complete in less than 0.1 second. Unfortunately there are times when they take longer. These longer ones are going to be the problem (I believe). As all activities are sequential servers can only catch up as fast as they can process them.
What i’ve found in the past 30 seconds is that it is not necessarily out database that is the problem but possibly the way lemmy handles the federation. I’m chatting with some of the admins on reddthat and making pretty graphs while looking at walls of logs.
I see, thank you for your work!
