SH> Hi everyone,

SH> I see reference to options: net.isr, msi-x, polling specially in ter,s of
SH> tuning and performance namely for packet processing/drops.

SH> I've searced (google, wiki and so on...) and I'm confused about these
SH> options and concerned about them since I'm working on routing and
SH> performance issues based on FreeBSD.

SH> can someone give light and detailed explanation about theseoptions,when
SH> should/shouldn't be used?

SH> Thanks in advance,

SH> Merry Christmas,

very good guide is here:
https://calomel.org/network_performance.html

polling is old. msi-x now give more better performance. see
descriptions in source code.
