No, otherwise we'd have heard a lot more complaints than yours.
You'll need to provide sufficient information to let someone else
reproduce the problem. This report is not even a start at that.
I would suggest doing some investigation to determine why things get
slower --- eg, is the system starting to swap heavily? Watching top,
vmstat, pg_stat_activity, etc would probably be informative.
