[dpdk-dev] About interrupts and packet loss

[Nulik Nol]

Hi,
I have read in a pdf document about DPDK that the driver that comes
within the DPDK distribution was modified to disable interrupt
handling. This explains why DPDK is so fast.
However , this means the app in user space must constantly watch for
new packets, so the CPU load average will be almost 100% all the time,
correct? Well, then what happens if the app executes a busy process
and at that time all RX rings get filled, will the incoming network
traffic be lost?

Thanks in advance
