Hi I am trying to compare the performance of sending packets using netmap, socket and packet mmap.
Right now I am working on top of pkt-gen and some other implementations for socket and packet mmap. I'm interested on the relation between packet size and packets I can send per second. I was following the code to check all the steps, and I found it is going throught a memcpy to set the packet on the netmap buffer (as defined on nm_pkt_copy inside netmap_user.h). I am afraid that the data I'm reading is mostly driven by the time the memcpy takes. Is there any other way around to check the performance in "send" to avoid this bottleneck? regards -- David Díaz Barquero Ingeniería en Computadores Tecnológico de Costa Rica _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
