I am a little guy; one connection an hour and I am *BUSY* Three concurrent connections is more than I will ever need. The limit is set low to fend off D-o-S attacks like the one I described.
By-and-large, default values are set to a reasonable value for a wide range of circumstances. However, I felt in my case, there was a special need to change it. I would not advocate frivolously changing a default value *before* it has proved to be unsatisfactory. Hope this helps.
