Will a jace-645 run a R2 station more efficiently than a UNC-520?


A UNC-520 is installed at a jobsite and has been programmed over the years with additional controllers and graphics.  The resource count is now over 600,000.  The CPU idle time does not rise any higher than 3-4%. 

Since the jace-645 is a more updated (i.e. powerful) hardware platform, will it run this large R2 station more efficiently?

Site UNC-520 can no longer run its installed station efficiently


Tridium tested the jace-645 and rated it capable of running a 600,000 resource-sized station.  It was not tested for anything larger.

Installing and running a larger R2 station is not recommended.
