I don't know if these settings seem high or low, but here's what I've got.

# cat /proc/sys/net/core/wmem_max
65535
# cat /proc/sys/net/ipv4/tcp_wmem
4096    16384   131072

The problem is, if I try to scan any more than a Class C, I get a "No buffer space available" error and the scan get's bogged down with 15 and 60 second pauses between scans.

You could try fiddling with /proc/sys/net/core/wmem_max or /proc/sys/net/ipv4/tcp_wmem to see if those buffers are the culprits.
