Lately a few folks have mentioned that they were unable to suggest edits because the queue itself was full. Apparently, the Suggested Edits queue is only allowed to contain 40 items.
That seems low for Ask Ubuntu which is busier than all but two of the other Stack Exchange sites (Stack Overflow's queue has a capacity of 500).
People frequently hitting the queue capacity limit before the per-user limit (a user is only allowed to have five pending edit suggestions) seems bad to me. While we could definitely use more active reviewers of several of the queues including Suggested Edits, I believe suggestions would still get cleared promptly if the capacity were increased. According to my stats about 3561320 reviews have been done in the last 730 days which(which is slightly over 5044 per day). This suggests that we could safelyI think it would be safe to increase the capacity of the Suggested Edits queue capacity to at least 50.
What do y'all think?
