Hi all,
While doing some 10Gb benchmark i've found that m_getjcl does not benefit from
the packet zone.
There is a ~ 80% increase in FPS when applying the following patch.
256B frame driver to driver / stable_8:
- 3 765 066 FPS
- 6 868 153 FPS with the patch applied.
Is there a good reason to not commit this ?
