Just loaded from SUP720-3BXL -> NPE-G1, 383k routes in under minute. And InQ
was almost all the time 0 in NPE-G1, as SUP720-3BXL wasn't sending fast enough.
Router had other session up, receiving 446k prefixes on that session.

NPE-G1# sh ip bgp summary
...
Neighbor        V    AS MsgRcvd MsgSent   TblVer  InQ OutQ Up/Down  State/PfxRcd
SUP720-3BXL     4  MAHAS  55538       5 119868995    0    0 00:00:59   383819

Took another 15s or so to hit 446k. But not interesting result, as SUP720-3BXL
is capping this.
NPE-G2 from same SUP720-3BXL hit 296k routes in 1min, and saw constant InQ,
hitting 446k in 1m50s

Both have large MSS size and no hold-queue drops and are running SRD4. However
NPE-G1 has base load of 1%/0%, NPE-G2 has base load of 17%/16%.
