Your questions indicate that you didn't read Tilghman's reply at all. 85 
users is not 'too many' for pretty much any Asterisk server you could 
imagine; on moderate hardware, Asterisk can easily handle a thousand SIP 
peers or more.

If your SIP peers are taking 234ms or longer to respond, then you need 
to adjust your configuration to treat that amount of time as 
'acceptable' and not 'unacceptable'. Changing the 'qualify' time to be 
300 (or higher) will do that.
