Very nice.. 30MB+/sec sustained for several minutes.. only 25% system CPU and the new profile is:
samples % symbol name 1047754 32.9054 pci_conf1_write 193876 6.0888 _spin_lock_irqsave 152897 4.8018 skb_copy_bits 74745 2.3474 _spin_lock 73273 2.3012 __copy_from_user_ll 69273 2.1756 __lookup_tag 65084 2.0440 _spin_unlock_irqrestore 43803 1.3757 sub_preempt_count 32047 1.0065 tcp_v4_rcv 30895 0.9703 schedule 26161 0.8216 kfree
