Discussion list for thrulay, a network testing tool

[stanislav shalunov <>]

Connie,

Excellent.  Does this meet your performance expectations (1.36Gb/s
single-stream and 2.31Gb/s with multiple streams)?  (I don't know what
the hardware is capable of.)  How does it compare with other testing
programs?

I suspect performance could be improved by setting the block size
higher than the default 8kB, maybe -l131072 or even more---this would
need experimentation.  Would you be willing to run several tests as
follows?

        for l in 8192 16384 32768 65536 131072 262144 524288 1048576;
        do thrulay -l $l hostname | fgrep "**"; done

(This should take about 8 minutes to run and produce 8 lines of
output.)  The results of this 8-minute test would help us tune the
default block size better, if needed.

An additional performance-enhancing avenue is TSC-based timekeeping,
which would halve the number of context switches in thrulay operation.

                                                              --Stas

P.S. Is it OK to forward your message to 

and copy this exchange there?  I think this might well be of general
interest.
