However, the trend is still growing and after about 40 minutes both putters had consumed all JVM memory and a full gc was invoked. I ran 2 senders at full speed on my WindowsXP laptop (1 CPU). I can only reiterate that they didn't run out of memory at all. I used both SUN's 1.4.2_05 and SUN's 1.5.0_01. The second test I ran for ca. 15 minutes, and memory even decreased slightly after a few minutes. Oh, I re-read your prev statement, you're not saying you run out of memory, but that you're seeing full garbage collections ? Then I suggest increasing the size of the young generation: JGroups creates a lot of smaller objects that can be garbage collected almost immediately after creation, e.g. Messages, Events etc. So the eden space should be relatively good-sized, so that the max number of bytes generated by Messages should be smaller than the eden space. >From the JGroups side, you can control the number of messages buffered though >FC.max_credits/min_threshold and STABLE.max_bytes. anonymous wrote : Next, I took your version of SimpleCacheTest.java (with the receiver flag = false, and the System.out.println output commented away) and your NetCache.java and reran the test with the fc-fast configuration. I should now be running virtually the same testbench as you (apart from the console output and your JBosscache 1.2.1 jar). When running two simple.bat putters simultaneously I eat up all 200 MBs of JVM memory in less than 5 minutes in each JVM triggering a full gc. In my tests, I didn't run with receiver=true because that would have generated less load.
