Hi Guys,
Can you please guide me to the performace reports of using various WMB Nodes.
1) Compute
2) XSLT
3) Mapping
4) Java
Thanks |

Please do not use those short url's. I know of several corporate firewalls where 'bit.ly' (and others) are blocked.

IMHO any such reports are nearly valueless if they even exist. Certainly for ESQL & Java the performance of the nodes is directly tied to the skill of the developer as you can write badly perfoming code in either.
I'd sooner select the node I use based on the kind of transformation that's needed, and the skill set of the developers; i.e. if you have a predominently Java shop with good Java people then it's pointless trying to get them to learn ESQL or XSLT.

Not quite. You have to get them to learn ESQL and XSLT the broker way. However the learning curve will be a lot less steep.
Have fun

Thanks Guys.
Do agree the dev standards would be diff for a beginner and expert.
But was looking to see which is more peformant.
esp ESQL, Mapping Node, XSLT, Java all doing similar processing. |

The answer is probably not XSLT which really gets up the nose of some Java devs I know (if the transformation is complex. simples ones may be faster but I tend to avoid XSLT if at all possible).

Your question is not really answerable. Which language is 'best' depends on how you ( or the organisation that you work for ) define 'best'. Raw speed is hardly ever the most important issue - regardless of what some may tell you.
Getting the design correct is almost always the biggest factor that affects performance.

From the IBM Report.
V8 introduces a new Mapping node which allows the user to visually map
and transform data from source to target. This new mapping node has
excellent performance characteristics, and is a viable option for
performance sensitive transformations. Some tests have been measured
performing close to optimised programmatic transformations in ESQL,
Java and .Net, with the typical measurement being 50%. Existing maps
developed prior to V8 will continue to work as-is, but will be opened as
read-only within the WebSphere Message Broker Toolkit. At the time of
writing this report, automatic migration of existing maps is not possible.
Trying to understand the statement..

does this mean the mapping node is 50% performant when compared to ESQL. |

No, it means that a fully optimized map is 50% performant to a fully optimized piece of ESQL. A badly written / optimized map will be less performant than that. A map trying to perform a complex transformation will be still less performant that a piece of ESQL that only needs 2 lines.

The correct translation of the IBM-speak:

is
| Quote: |
| The new mapping node doesn't suck like the one in v6 & v7, and you can now consider it for performance sensitve transformations when in v6 & v7 you just ruled it out of those use cases because it sucked so badly |

| Actually, the GDM should run on par with ESQL or Java. That performance report is out of date, if I recall correctly. |

You missed your calling as a Copy Editor for Technical Journals.
