You can find a microbenchmark suite for RMI, as well as object
serialization, in the "test" tree of the jdk7/jdk repository--
relative to the jdk7 forest, look here:

        jdk/test/java/rmi/reliability/benchmark

There isn't much documentation there, but the script here:

        jdk/test/java/rmi/reliability/scripts/create_benchmark_jars.ksh

shows how to create two JAR files, rmibench.jar and serialbench.jar
from the sources.  Running either JAR with "-h" prints a usage
message.  Each has a default config file that can be altered to
customize which of the microbenchmarks to execute, how many
repetitions of each to run, how much warmup to do, etc.  The RMI suite
can be run all in one VM or in two separate VMs, a "client" and a
"server", possibly on different hosts.
