I have done some performance tests and have compared two scenarios.
1. Getting 100,000 times 8 properties from an mbean.
2. Getting 100,000 times 8 propeties by a simple getter method.
My results are like this :
10:55:08,535 INFO [STDOUT] property Time :31 msec
10:55:44,913 INFO [STDOUT] JMX Time :36378 msec
does that means I should cache the configuration properties i get from MBeans? or is
there something bad with my code?
A sample code of getting a property from an MBean that I used :
| public String getEmailProtocol() {
| String value = "imap";
| try {
| value = _mBeanServer.getAttribute(_objectName, "EmailProtocol").toString();
| } catch (AttributeNotFoundException e) {
| _log.error(e.getMessage(), e);
| } catch (InstanceNotFoundException e) {
| _log.error(e.getMessage(), e);
| } catch (MBeanException e) {
| _log.error(e.getMessage(), e);
| } catch (ReflectionException e) {
| _log.error(e.getMessage(), e);
| }
| return (value);
| }
