Hi All, The performance of JBoss Expert and Fusion is fine. The throughput of JBoss Expert and Fusion is about 9900 and 4500 messages per second. But we meet the following problems. When the number of handled messages is about 500,000, the performance of Expert is very slow. Its memory is about 300 Mbyte. When the number of handled messages is about 300,000, the performance of Fusion is very slow. Its memory is about 300 Mbyte. What is the problem? How can we solve it?

No. We do not keep the 300K and 500K facts or events in the working memory. We use retract to remove the fact and events, or we set the expire value in events. 300K is the total number of the handled message. OK. We will take a look at GC(garbage collection) frequency. How can we solve the GC frequency in JBoss Expert or Fusion? Should we set the GC frequency in Java or JBoss?

The difference you are reporting is bound to be due to different Event types and different rules. There are several possibilities why things slow down. Have you analysed your application's behaviour using the usual monitors, e.g., to learn about GC frequency? Do you need to keep 300K or 500K facts in WM? -W On 25/05/2012, Kang Heng WU <khwu(a)astri.org&gt; wrote: > Hi All, > > The performance of JBoss Expert and Fusion is fine.
