====== Networking - Tuning and Troubleshooting Network Cards - Packet loss with many (small) UDP packets ======

If you see a lot of packet loss with UDP on bce cards, you might also try changing the netisr settings.

These can be set as system tunables under **System -> Advanced**, on the System Tunables tab.

On that page, add two new tunables:

<code>
net.isr.direct_force=1
net.isr.direct=1
</code>
