Both are right.  :)  Almost anything greater than 0.4 will be fine.  Be
careful with the CVS tarballs, I've had some folks who can't compile from

If running on a Linux based system, you might want to check out Phil
Wood's "Burnt Offerings" [0].  You can find one very nice libpcap patch
for Linux 2.4.x kernels that adds MMAP, ring buffers and supports
TurboPacket.  From what people have said, there is usually a gain from
using the patches.  I don't run a Liunux based box so I haven't gotten a
chance to beat on it myself.

Hope that helps!
