Re: [rules-users] high cpu usage

The figures you gave just indicate that you have a good balance between I/O and CPU load. The increase between "no rules" and "~60 rules" is to be expected as all the work is being done during fact insertion. Of course, adding more and more rules will, eventually, push the CPU load factor to the natural upper limit. If the overall throughput is good, why do you worry? -W On Tue, Mar 24, 2009 at 11:20 PM, techy <techluver007(a)gmail.com&gt; wrote: Hello My app is functioning consumer/producer model. 1.Producer reads the data from DB and inserts to blocking queue 2.Consumer reads the data from queue and execute the rules using drools stateless session. Both producer and consumer run asynchronously. in my testing I found the following 1. for 1000 facts at a time and no rules in drl, cpu usage is maintained at 25-30% in my PC(Intel core 2 CPU,2.13 GH,2G RAM) - with no rules in drl, Is this cpu usage acceptable? 2. for 1000 facts at a time and ~60 rules in drl, cpu usage is maintained at 50-60% on the same PC. 3. If I have 1 sec wait between each execution of rules in consumer, then cpu usage is maintained < 5% high CPU usage is being big concern to me. Is this expected while using drools? Do others see same cpu usage too? Please share your thoughts. appreciate your input.
