Hi, I am transferring 1 Million packets from send process to receive process. Both are running in separate cores. I am using Using DMA transfer from usermode to the ethernet card.
After transfer I can see 700 - 800 packets loss per transaction. I doubt that during the transfer kernel may be entering some spinlocks or descheduling the receiver processor for long enough. Please can you share how can I debug this case. Please share as to what approach I can take to detect that. The time involved in the tranfer is very less around 1 Million packets per second and in that second packet loss is happening.
