Just a general observation I've made in my time on lemmy.ml, which I figure is attributable to lemmy the software, that may or may not be useful.
I'm talking about writing comments to posts (or replies to other comments, not sure if I've seen a difference).
And, just anecdotally, it seems that the longer the instance has been up without a restart or update (AFAICT of course), the longer the time between me clicking the Reply
button and the time that the request is completed.
Usually, the first sign in my experience that the instance has been restarted is that this latency speeds right up to being almost instantaneous.
Anyone else notice the same or on other instances? It might be a clue to performance issues??
EDIT: applies to posts too (including this one incidentally)
