Hello, @rjmcmahon Thank you for response. I guess based on my understanding, iperf2 uses write() function now to send TCP packet in client and write() function does not support zero-copy. Please let me know after you take a look again.

Do you have any plan to support zero copy on tx ?

Hello, @rjmcmahon Thank you for adding this feature. Based on my understanding, now it skips only rx copy. Based on my understanding, iperf2 uses write() function to send TCP packet in client and write() function does not support zero-copy. Do you have any plan to support zero-copy on TX (SO_ZEROCOPY/MSG_ZEROCOPY)? Thanks
