Pinned topic A difference between a 'work factor' and a 'speed factor'

‏2012-10-18T09:23:10Z |
Hello,

I would like to ask about difference between a 'work factor' and a 'speed factor' on WAS V8.5 ND.
In the V8.5 InfoCenter, the following passages are described.

http://pic.dhe.ibm.com/infocenter/wasinfo/v8r5/index.jsp?topic=%2Fcom.ibm.websphere.wve.doc%2Fae%2Ftwve_arfmworkfactor.html

If you have already specified a speed factor override, you do not need to configure a work factor override. For more information about speed factors, read about configuring work factors in multiple tier configurations.

From the description above, I guess a 'speed factor' is different from a 'work factor'.
But, there are no descriptions about a 'speed factor' in the InfoCenter, meanwhile there are some descriptions about a 'work factor'.
Can anyone tell me the difference between a 'work factor' and a 'speed factor' , please?

Thanks in advance.

    The reference to speed factor needs to be deleted from the description, it is old terminology that is no longer used.

    Hello, Allan

    Thank you for your response.
    I would like to ask two more questions.

    (1)
    I remember that there used to be two components in a work profiler, one of them is an alpha estimator to calculate work factors, the other is a kappa estimator to calculate speed factors.
    Am I correct in assuming that there is the only alpha estimator in a work profiler in WAS V8.5 ?

    (2)
    I remember that a work profiler use to be a part of ARFM in WVE V6.0.
    But in a WAS V8.5 adminconsole, we can look at "Work Profiler Controller" from Runtime Tasks menu.
    Am I correct in assuming that a work profiler is separated from ARFM ?

    Regards,
    Namie
