Hi, I am setting up a prototype to evaluate our re-engineering project. I need a cache system to hold the transaction data and I've choose JBoss Cache after browsing the website. So I am new to JBoss Cache and I meet a problem in setting up using the FileCacheLoader. My intension is to first setup a simple Cache with file persist for fail over recovery. Everything seems working fine untill I set up a FileCacheLoder. The problem is it becomes SO SLOW for putting entries after set up the FileCacheLoader. I have a testing program that simply write and read some objects to the same cache node in a loop. Before I set up the FileCacheLoader, it take only about 1-2ms to read/write an object. But after using the FileCacheLoader, it takes 100ms to write an entry in the beginning and the time keeps growing and finally reach about 1000ms per write. I know there must be some performance degrade after using cacheLoader but this kind of degrade seems not right . Can somebody take a look at my configuration file as following, Thanks a lot ! Besides, will a JDBCCacheLoader provide better performance ? It will be greatly appreciated if somebody can provide samples for that . =========== jbosscache-config.xml ========== | | <server> | | <classpath codebase="./lib" archives="jboss-cache.jar, jgroups.jar"/> | | <mbean code="org.jboss.cache.TreeCache" name="jboss.cache:service=TreeCache"> | | <depends>jboss:service=Naming</depends> | <depends>jboss:service=TransactionManager</depends> | | <attribute name="TransactionManagerLookupClass">org.jboss.cache.DummyTransactionManagerLookup</attribute> | | <attribute name="IsolationLevel">REPEATABLE_READ</attribute> | | <attribute name="CacheMode">LOCAL</attribute> | | <attribute name="ClusterName">TreeCache-Cluster</attribute> | | <attribute name="ClusterConfig"> | <config> | <!-- UDP: if you have a multihomed machine, | set the bind_addr attribute to the appropriate NIC IP address | --> | <!-- UDP: On Windows machines, because of the media sense feature | being broken with multicast (even after disabling media sense) | set the loopback attribute to true | --> | <UDP mcast_addr="228.1.2.3" mcast_port="45566" ip_ttl="64" ip_mcast="true" | mcast_send_buf_size="150000" mcast_recv_buf_size="80000" ucast_send_buf_size="150000" | ucast_recv_buf_size="80000" loopback="false" /> | <PING timeout="2000" num_initial_members="3" up_thread="false" down_thread="false" /> | <MERGE2 min_interval="10000" max_interval="20000" /> | <FD shun="true" up_thread="true" down_thread="true" /> | <VERIFY_SUSPECT timeout="1500" up_thread="false" down_thread="false" /> | <pbcast.NAKACK gc_lag="50" max_xmit_size="8192" retransmit_timeout="600,1200,2400,4800" up_thread="false" | down_thread="false" /> | <UNICAST timeout="600,1200,2400" window_size="100" min_threshold="10" down_thread="false" /> | <pbcast.STABLE desired_avg_gossip="20000" up_thread="false" down_thread="false" /> | <FRAG frag_size="8192" down_thread="false" up_thread="false" /> | <pbcast.GMS join_timeout="5000" join_retry_timeout="2000" shun="true" print_local_addr="true" /> | <pbcast.STATE_TRANSFER up_thread="false" down_thread="false" /> | </config> | </attribute> | | <attribute name="SyncReplTimeout">10000</attribute> | | <attribute name="LockAcquisitionTimeout">15000</attribute> | | <attribute name="EvictionPolicyClass"></attribute> | | <attribute name="CacheLoaderConfiguration"> | <config> | <passivation>false</passivation> | <preload>/test</preload> | <shared>false</shared> | | <cacheloader> | <class>org.jboss.cache.loader.FileCacheLoader</class> | <properties> | location=/tmp/filetore | </properties> | <async>true</async> | | <fetchPersistentState>true</fetchPersistentState> | <ignoreModifications>false</ignoreModifications> | <purgeOnStartup>false</purgeOnStartup> | </cacheloader> | | </config> | </attribute> | | </mbean> | </server> ===== Testing Program ===== | | TreeCache cache = new TreeCache(); | PropertyConfigurator pc = new PropertyConfigurator(); | pc.configure(cache, "jbosscache-config.xml"); | | cache.createService(); | cache.startService(); | | cache.put("/test", key, obj ); | | ....
