how to calculate the bandwidth(speed) from report result，i hope the result is kile 5Gbps
i use goben test vm1 to vm2 bandwidth，got result like this

The bandwidth is always reported in Mbps (Megabits per second).
Hence your client read 1827 Mbps (1.827 Gbps) on average, and wrote 19026 Mbps (19.026 Gbps) on average.
and can i get the lost package percent from the test result
No, you can't, since the software does not track statistics about lost packets.

tks for your reply, first question is my fault, and tks your project again.
i want get some advice on how to test the maximum bandwidth method from you, now i try to get the max bandwidth by use different cpu process num, i think maybe we can define the fixed bandwith to do the perform test. Put it another way, if use goben to test and git a result, how can i confirm it is the best bandwidth?
Looking forward to your answer, tks very.

oh, i remember now, Is it possible to compare with clientReader and clientWrite to confirm the max bandwidth，because i find when clientReader equal clientWrite the lost package is 0%，most question expose on udp protocol，tcp protocol is reliable.
@phygerr I would try different things in order to find the highest possible rate, like:
1 - start with a single tcp connection 2 - increase the number of tcp connections gradually until the rate starts to drop 3 - now you should have an idea of the max possible rate you could attempt to increase by using udp with rate limit
You can also attempt to tweak buffer sizes.
Something like that.
