Hi all, I am a beginner of DPDK. Recently, i am interest in DPDK vHost app - testpmd.
And i have been tracing on testpmd.c and iofwd.c for a while. Also add some code inside iofwd.c for storing the payload of packets. Everything goes fine, and the performance is great as expected. But when i use fwrite to store the payload into a file, the performance decrease from 800mbps to 3mbps (input stream is 1 Gbps). Is is caused by the limitation of Virtual Disk IO? How can i solve it? I have tried to search the answer, some people say "pthread" might solve the problem. Can someone give me some hint, i really appreciate for your help. Best Regard, Kevin Cheng
