You do not need to micro-control this. The wrk provides you with nice stats plus you have counters of "systat -ifstat 1" during long test. > All these tools — wrk, nginx — are optimized for many concurrent > connections on powerful hardware and looks like overkill to test one > connection bandwidth on Atom CPU. You can choose number of concurrent connections yourself while running wrk. > BTW, how to configure nginx to server 16G+ file without any disk access? > One big hole on tmpfs? :) You do not need large disk file in case of wrk+nginx. Make small-sized tmpfs with single several megabytes-sized file, and that's all. _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
