+ *       3 Currently a lot of packets(~17k) are getting stuck on the detection
  *         thread, which is a major bottleneck.  Introduce bypass detection
  *         threads for these 15k non buffered packets and check how the alerts
  *         are affected by this(out of sequence handling by detection threads).
- *       - Use texture/shared memory.  This should be handled along with AC.
+ *       4 Test the use of mapped memory(if possible anywhere).
- *       - Test the use of host-alloced page locked memory.
+ *       5 Check parallelising memcopies with kernel execution.
- *       - Test other optimizations like using the sgh held in the flow(if

- *         present in the flow), instead of retrieving the sgh inside the batcher

+ *
+ *         Modify the block size to 16 threads for CC < 2.0 devices and 32 for
+ *         for >= 2.0.
+ *
+ *         The rearrangement of packet stream can be done on the gpu, with no
+ *         perf degradation, using coalesced reads.  Padding packets need to
+ *         be addressed though.

+ *         drop a mail to dev mailing list(or directly to the dev team).  Better
+ *         yet, open a feature request on our bug/feature tracker
+ *         (https://redmine.openinfosecfoundation.org/issues).  Will be a mess if
+ *         2 or more devs end up working on the same task or related tasks.
