10Mpbs ? You're going to get 1MB/sec throughput max. If you run only on the local box, set UDP.bind_addr to 127.0.0.1, to circumvent the NIC entirely. Also add a multicast route that actually points to your loopback device. I suggest you take the NIC down for the duration of the tests to make sure you don't send anything via the 10Mbps link. Also, I suggest to set UDP.loopback=true. anonymous wrote : | - will have gigabit within the next few weeks with dual 3.0ghz xeon machines if that will make a big impact? A huge difference ! JGroups is CPU-bound with 1 CPU, with 2 CPUs I saw a huge diff in my tests. I was actually able to almost saturate the network (9MB/sec on a 100Mbps switched ethernet), with 10K msgs. I haven't tested GB ethernet yet, but the numbers there should actually be even better. Here's another one: you may want to adjust the compression level in COMPRESS (9 = best). anonymous wrote : 1 pub - 1 sub | 678 messages/second at 10,000 text messages sent | | 1 pub - 2 sub | 460 messages/second at 10,000 text messages sent | | 1 pub - 3 sub | 345 messages/second at 10,000 text messages sent I would expect about the same msg rate. What happens though, is that you could have a lot of retransmissions (which are unicast). Can you run tcpdump/snoop/ntop to see what your traffic is ? I'd expect mostly multicast; if you have a large number of unicast UDP traffic, then you have too many xmits. anonymous wrote : For Object messages using my implementation of the ObjectMessage (all of which use the fc-fast.xml stack) | These messages are a series of state vectors packed in a java.util.Arraylist (written to a file as an ObjectOutputStream each fille Arraylist produced 1.8kb of data) Same test, with ObjectMessages ? I have to conclude it is serialization then. Can you do some intelligent marshalling of the vectors, and then use BytesMessage ?
