I am testing JGroups 2.6.5 with sequoia_jgroups.xml, which comes with
Sequoia 4, the up-to-date version.
With the normal udp.xml of JGroups, Perf test works perfectly. BTW, when I
use the xml of Sequoia 4, the Perf test doesn't work. It just hangs. I am
using Gigabit switch. And, to expose which tags make this problem, I added
one tag by tag to the working udp.xml. Then, after I put SEQUENCER tag, the
Perf test stops working.
To make sure this problem, I removed SEQUENCER tag from sequoia_jgroups.xml.
And then, the perf test starts working. Some parts of its result showed
63MB/sec performance, which is much better performance than normal udp.xml.
Definitely, this problem is caused by SEQUENCER tag. Do you have any idea?
Thanks.
