To be honest we haven't done much more performance testing, but the
packet batching code is now there i.e. sending multiple packets at
once to the graphics card.  If you have the cycles take it for a spin
and let us know ;-)..  We will be doing more testing/refining of this
code but as of now it is still experimental.  Just to rehash to build
with cuda support you simply...

./configure --enable-cuda

edit the suricata.yaml file and set

mpm-algo: b2g

to

mpm-algo: b2g_cuda

and

#max-pending-packets: 50

to something like

max-pending-packets: 7500

This will cost you some ram btw ;-)

Will
