Hi All,
i am new to QPID, after downloading the software from website, i used the
sample example code (recv.c and send.c) and modified on send side to
continuouly send 64 bytes packets from machine A and on recevie side on
machine B grabbing the packet and checking how much packets i received per
sec and i am not able to see more than 18000 packets per sec (throughput
10Mbps).
being a 1Gbps link between two machines i was hoping for more throughput
coming out of it..
i ran standard TCP performance test and it get close to 800Mbps throughput.
can someone please suggest if there is something obvious that i am missing
or there exist some performance script which help me understand what is
causing low throughput..
There are two test programs that report throughput and latency for
different scenarios. The executables are built under
<build>/tests/tools/apps/c/ and are called msgr-send and msgr-recv.
E.g. for a one-way test, start
/tests/tools/apps/c/msgr-recv -c 1000000
then in another console:
/tests/tools/apps/c/msgr-send -c 1000000 -b 64
The message size is controlled with the -b option. You can vary the
batch size for send with -p option. You can also run a two way test,
where the receiver echoes the messages back using the -R option to each.
By default messages are sent presettled, you can change that by setting
a non zero outgoing window with the -w option.
On my laptop, over loopback, I get about 50k 64 byte msgs/sec using the
default batch size of 1024. With a batch size of 1, that drops to about
25k msgs/sec.
Rafi, Ken, can either of you give an indication of what you would expect
to see?
