> @a-lunev do you have any perf number with/without this feature? Based on the current state of sim:tcpblaster config, the results are as follow: 1. CONFIG_NET_TCP_WRITE_BUFFERS=n, CONFIG_NETUTILS_NETCAT_SENDFILE=n, file size is 500 KB, the payload throughput is 205 Kbit/s. 2.a. CONFIG_NET_TCP_WRITE_BUFFERS=n, CONFIG_NETUTILS_NETCAT_SENDFILE=y, file size is 500 KB, the payload throughput is 4.1 Mbit/s. 2.b. CONFIG_NET_TCP_WRITE_BUFFERS=n, CONFIG_NETUTILS_NETCAT_SENDFILE=y, file size is 1000 KB, the payload throughput is 8.19 Mbit/s. 3. CONFIG_NET_TCP_WRITE_BUFFERS=y, CONFIG_NETUTILS_NETCAT_SENDFILE=n, file size is 500 KB, the payload throughput is 36.7 Kbit/s. 4. CONFIG_NET_TCP_WRITE_BUFFERS=y, CONFIG_NETUTILS_NETCAT_SENDFILE=y, file size is 500 KB, the payload throughput is 4.1 Mbit/s. If CONFIG_NETUTILS_NETCAT_SENDFILE=y is enabled, the larger file size, the higher speed. -- This is an automated message from the Apache Git Service.
