Hi jaders,
I have tried the benchmark addon for JADE, with JADE-LEAP 2.5 and java 1.3.1.03 (without just-in-time compilation). I have run it on a PIII 933 HP Kayak with 100 Mbits ethernet card. When I run the bench with one Jade platform, one host, and one or two JVM, the results I have obtained are very close to the results of the paper "Scalability and performance of JADE Message Transport System". But when I try to run the bench between two hosts, unfortunaly without a proper network for my two hosts, my results (average RTT) are higher, with a 20 factor !!! For example, with 2 hosts, only 15 couples and 1000 messages are exchanged by each couple, my average RTT is 6569 ms ! It should be around 300 ms according to the same paper. I know my network is not dedicated to my test, but the difference is too important. Is LEAP changing the transport mechanism ? I have exactly the same average RTT between my PC and an iPAQ running Jeode VM with 10 Mbits ethernet card ! Does anybody know why ?
Thank you very much for your help.
