[jboss-user] [JBossCache] - Clustered-cache memory utilization issues

Hi there, I?m experiencing some wired behavior in the JBoss Cache, regarding its memory management. Please have a look on the following scenario: 1. Machine A creates a cache (a-sync mode). 2. Machine A creates 50,000 objects (Each ? 1K). 3. Machine B joins the cache. 4. Machine A puts all 50,000 objects to the cache. 5. Machine B gets all nodes to its local memory. 6. Kill the application on machine B (). 7. Machine B start the application again, and joins the cluster. 8. Kill the application on machine B (). 9. Machine B start the application again, and joins the cluster. 10. Kill the application on machine B (). 11. Machine B start the application again, and joins the cluster. 12. Kill the application on machine B (). 13. Machine B start the application again, and joins the cluster. For each step, I?ve measured the time (in MS) and the memory utilization. Some of the results: Average time to insert the nodes (by machine A) - 19,842.60 ms Average time to recieve all the nodes (by machine B) - 30,673.60 ms Average time to machine B to start (with loading all the cache data) - 18,954.50 ms Average memory usage to empty cache - 87.11 mb Average memory usage by objects (not in the cache) - 198.40 mb Average memory on machine A after step 5 - 550.40 mb Average memory on machine B after getting all data - 400.40 mb Average memory on machine A after step 7- 859.40 mb Average memory on machine A after step 8- 908.20 mb Average memory on machine A after step 11- 926.20 mb Average memory on machine A after step 13- 931.00 mb So my issues: It appears that each time machine B restarts, the memory utilization on machine A gets higher? Mainly I?m concern about the first time machine B stops and restarts. It takes the memory utilization on machine A from 550.40mb to 859.4mb? Another issue is the time that machine B takes to load all cache? ~19 sec. Is that what I need to expect? BTW, I?m using twi machine, both with Linux Red-Had Advance server 3 rc5. I'm using the top command to monitor the memory utilization for the processes. Thanks, Gilad. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3988776#...
