Ask for a "BGP Summary" from any looking glass and look for the higest
PfxRcd (Prefixes Received) numbers. E.g.:

http://www.linx.net/tools/stats/looking-glass.thtml?run=true&site=LINX-Transit&query_type=+BGP+Summary&address=&Submit=Submit&.cgifields=query_type

BGP router identifier 195.66.227.254, local AS number 5459
[snip]
 Neighbor        V    AS MsgRcvd MsgSent   TblVer  InQ OutQ Up/Down  State/PfxRcd
[snip]
 195.66.248.10   4   702 10749979  604899 56276301    0    0 4w1d       118116
 195.66.248.18   4  5378 6693858  403755 56276350    0    0 4w1d       118154
 195.66.248.26   4  2529 82684567  372887 56276346    0    0 4w1d       119017
 195.66.248.34   4  5413 11105551  403902 56276301    0    0 19w3d     118590
[snip]

So, currently around 120,000 prefixes (routes) in the global routing table
for a full feed.
