By gateways ? It isn't clear.

It really depends what you expect to catch :
- Between router and firewall : bad external traffic coming on your network
- On your DMZ : bad traffic your firewall let come in
- On your local network : Policy enforcement, backdoor infected local systems, etc.

Again, it depends on the network load, the CPU speed, the disk speed, the OS, the weather, etc.
'-b' beeing the fastest, you simply lower the risk of missing packets.
Hope this helps
