I'm going based on actual tests done when the ERL came out in 2012. 
While its cores are anemic by today's standards, it handled multiple 
full tables fine back then.

Since then, the ERs have stopped using Quagga/Zebra and now use ZebOS 
(which is also used in several other commercial products).  It's a bit 
faster and smaller.

In today's world, its tight, but it will still work.

As I pointed out, its the dirt cheap option.  Better option is the ER4 
and later which is better suited to the increased table size.
