Iperf has a few problems.

Re: Throughput test with iperf...
thanks for your reply.. :) i think it's iperf.. i installed /usr/ports/benchmarks/iperf port. where can i find iperf2? my machines are both FreeBsds but i can't find iperf2 in my ports collection..

Re: Throughput test with iperf...
hi again.. would any of you please at least explain it to me what may cause iperf server ending up with "Segmentation fault (core dumped)" message right at the beginning of setting second connection in my bi-directional throughput test, using -r flag?? i used these commands on client and server on two freebsd machines which are connected straight with one cat5e cable: iperf -s -i 1 iperf -c X.Y.Z.T -t 60 -r just getting more confused.. :( Best Regards, t.a.k On Sat, Sep 28, 2013 at 10:22 AM, takCoder wrote: > hi everyone, > > this might be a bit off-topic but i am really confused and in need of your > helps.. :( > > i need to understand what exactly iperf does while testing network > throughput? > > i'm trying to run a throughput+frame loss test on a router using iperf, > and i am really confused with the definitions given for throughput and > packet-loss and iperf output.. > > as i have seen through my searches, throughput is the maximum transfer > rate at which we have no packet loss, so i thought i have to rerun iperf > for different transfer rate(in udp test), so i reach maximun rate while > having no drops... > > but i have seen test videos in which they ran iperf once, with maximum > bandwidth of the line, and just used the reported throughput and packet > loss as the required result! > > what's on? does iperf calculate the throughput independent from > packet-loss? and why is it reporting it named as bandwidth?? > > thank you all.. > > Kind regards, > takcoder > ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
Throughput test with iperf...
hi everyone, this might be a bit off-topic but i am really confused and in need of your helps.. :( i need to understand what exactly iperf does while testing network throughput? i'm trying to run a throughput+frame loss test on a router using iperf, and i am really confused with the definitions given for throughput and packet-loss and iperf output.. as i have seen through my searches, throughput is the maximum transfer rate at which we have no packet loss, so i thought i have to rerun iperf for different transfer rate(in udp test), so i reach maximun rate while having no drops... but i have seen test videos in which they ran iperf once, with maximum bandwidth of the line, and just used the reported throughput and packet loss as the required result! what's on? does iperf calculate the throughput independent from packet-loss? and why is it reporting it named as bandwidth?? thank you all..
