That is the $64,000 question. If you stick to CW spots, so far, I have 
seen about ~10/sec during the last big contest. We will see what this 
weekend brings for a more definite answer. I would be quite surprised to 
see 100 spots/sec or 8200 bytes/sec. But remember, the most you are 
likely see coming out is ~820 bytes / sec / RBN Spot user and. even on 
the last big CW contest the actual "curated" output was 1 or 2 / sec, 
but not consistently. 30000 incoming spots / hour would be whittled down 
to about 3000/hour or about 8 every 10 seconds.

I am waiting with bated breath how WA9PIE-2 copes with 1000+ users. 
Human spots is no problem at all, it trundles along at about 2-7% CPU on 
a big contest.  But it is unlikely that (anything like) that many of 
them will using the RBN feed - at least this weekend. But we will see. 
1000 * 820 is how many bytes/sec again...?

But I would strongly recommend that you upgrade, just for the improved 
speed and reduced power consumption. Whether you connect to the RBN is a 
separate issue. The 'mojo' branch is where it is all at. The 'master' 
branch is now just in care and maintenance. All new features will go 
into the 'mojo' branch (there is a clue as to what it is in UPGRADE.mojo),
