Bela , thanks for your reply. I just test replicating performance under solaris platform, meet some question.
Steps: Start up first jboss cache , inserted 100,000 objects into it , the object size is about 500 bytes. The inserting time is about 10 secs. ------------------------------------------------------- GMS: address is fire1:38833 ------------------------------------------------------- 16:57:36,433 INFO [TreeCache] viewAccepted(): new members: [fire1:38833] 16:57:36,447 INFO [TreeCache] state could not be retrieved (must be first member in group) 16:57:36,447 INFO [TreeCache] setState(): new cache is null (maybe first member in cluster) time = 10319 data size 100000 then start second jboss cache to backup the contents of the first , the replicating time is about 20 secs. 17:03:56,372 WARN [AckReceiverWindow] discarded msg with seqno=6232 (next msg to receive is 6558) 17:03:56,373 WARN [AckReceiverWindow] discarded msg with seqno=6278 (next msg to receive is 6558) 17:03:56,373 WARN [AckReceiverWindow] discarded msg with seqno=6360 (next msg to receive is 6558) 17:03:56,374 WARN [AckReceiverWindow] discarded msg with seqno=6412 (next msg to receive is 6558) 17:03:59,545 INFO [TreeCache] setState(): locking the old tree 17:03:59,567 INFO [TreeCache] setState(): locking the old tree was successful 17:03:59,568 INFO [TreeCache] setState(): forcing release of all locks in old tree 17:03:59,568 INFO [TreeCache] state was retrieved successfully (in 21450 milliseconds the memory usage on first 1597 hanson 26 29 10 570M 474M sleep 0:21 0.95% java the memory usage on backup 18990 hanson 24 28 10 566M 277M sleep 0:10 0.03% java if insert 400,000 objects, inserting time is about 40 secs ------------------------------------------------------- GMS: address is fire1:38856 ------------------------------------------------------- 17:03:55,271 INFO [TreeCache] viewAccepted(): new members: [fire1:38856] 17:03:55,291 INFO [TreeCache] setState(): new cache is null (maybe first member in cluster) 17:03:55,292 INFO [TreeCache] state could not be retrieved (must be first member in group) time = 40046 and replicating time is about 100 secs 17:13:46,654 WARN [AckReceiverWindow] discarded msg with seqno=25746 (next msg to receive is 26175) 17:13:46,655 WARN [AckReceiverWindow] discarded msg with seqno=25810 (next msg to receive is 26175) 17:13:46,655 WARN [AckReceiverWindow] discarded msg with seqno=25852 (next msg to receive is 26175) 17:13:46,655 WARN [AckReceiverWindow] discarded msg with seqno=26036 (next msg to receive is 26175) 17:14:00,739 INFO [TreeCache] setState(): locking the old tree 17:14:00,763 INFO [TreeCache] setState(): locking the old tree was successful 17:14:00,764 INFO [TreeCache] setState(): forcing release of all locks in old tree 17:14:00,764 INFO [TreeCache] state was retrieved successfully (in 98070 milliseconds data size 400000 the memory usage on first 23659 hanson 26 29 10 1881M 1632M sleep 1:37 0.12% java the memory usage on backup 19012 hanson 25 28 10 613M 579M sleep 0:35 0.16% java My Question is [1] why the first jboss cache eat so much memory after replicating? before replicating, it only eat about 560M memory 26793 hanson 24 29 10 566M 320M sleep 0:41 8.87% java [2] when insert 800,000 objects into first cache , then start backup cache. I found the repli cating failed in 500 sec .However, the first jboss cache eat almost all memoy (1800M) [3] Is there any way to improve the performance when replicating huge volume data (>500M)? How many meomory required?
