Re: [sensor-dev] Results of very simple performance test + reported Jamon values are false

[Jeroen B. <jbo...@xe...>]

Hi Age,

Sounds great, but I am not convinced.

How did you test the JAMon performance?
The JAMon page refers to com.jamonapi.TestClassPerformance, it also uses 
a monitor around the test with the loop (of 1.000.000 iterations),
the last code block:
        timingMon.start();
        test.factoryMonitor();
        log(timingMon.stop()); :

Gives me the next output:
----
Full Factory TimingMonitor()- uses cached version so doesn't create 
child monitors
    Monitor mon=MonitorFactory.start('pages.admin');
    mon.stop();
JAMon Label=pages.admin, Units=ms.: (Hits=2000000.0, Avg=7.0E-5, 
Total=140.0, Min=0.0, Max=16.0, Active=0.0, Avg Active=1.0, Max 
Active=1.0, First Access=Mon Mar 20 10:28:02 CET 2006, Last Access=Mon 
Mar 20 10:28:05 CET 2006)
It took 1594 ms.
----
The JAMon label Avg=7.0E-5 is bogus because of the clock resolution as 
you point out. However, the time all 1.000.000 iterations took is: 1594 ms.
This means 627.000 calls per second on my 5160 laptop with jdk 1.4.2.

So, I would say the numbers on the JAMon page are correct (405.000 
calls/s for jdk1.4). Agree?

Ciao,
Jeroen.

PS. I haven't had time to time Sensor yet.

Re: [sensor-dev] Results of very simple performance test + reported Jamon values are false

[Jeroen B. <jbo...@xe...>]

Hi Age,

Okay, I've installed the svn Eclipse plugin and checked out Sensor and 
achieved to get it running in Eclipse. :-)

I run the jUnit test in Eclipse of SimplePerformanceTest. The second 
time I tested it, I got:

Total time (parent timer): 937 ms.
Number of hits (test timer): 1000000.
Total time (test timer)    : 125 ms.
Average time (test timer)  : 0 ms.

So, this is even better than JAMon!
1.067.000 calls/s.

Not bad!

How much time did it take on your laptop?
If it is so much slower for you, I would consider switching to another OS!

Jeroen.

Re: [sensor-dev] Results of very simple performance test + reported Jamon values are false

[Jeroen B. <jbo...@xe...>]

Hi Age,

How did you calculate the factor of 4?

1M iterations with start-stop:
Sensor: 937 ms.
JAMon: 1594 ms.

So, Sensor time = 59% of JAMon, so Sensor is 41% faster than JAMon.

Or am I missing something?

Ciao,
Jeroen.
