Posting replies takes forever, multiple attempts creates multiple posts.

I had this issue prior to whatever significant changes were made about a week or so ago that improved the performance of Lemmy.world. I'd try to create a new post or reply to an existing one. On hitting submit/reply, the spinning wheel would appear on the button icon and after waiting minutes, I'd refresh. Sometimes the post or reply would be present, other times not. With replies in particular, I'd make multiple tries and over time, the aborted attempts would result in a series of replies.

Is there a performance issue server side that is the cause for this behavior? Is there anything I can do from my end to troubleshoot? One thing that is different between now and then is that upvoting or downvoting posts is fast and responsive. Before the changes using those buttons amounted to the same thing, lag/non-responsiveness.

Regardless of the issues, I'm enjoying Lemmy.world! Keep up the good work.
