Hey guys,
Have you experienced any performance issue in WMB6.0 for XSLT transformation.
All i am doing is sending a message 800KB message to XSLT node. I am not doing any transformation. But it consistently takes 2- 4 seconds.
Any suggestions?
i know WMB6 is going out of support, but we are only migrating end of this year to production. till then we have to live with this lag.
This is all i have in the XSL file.
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
</xsl:template>
</xsl:styplesheet>
here are the timings from the trace nodes
1.7 MB 3.3 s
1 MB 2.2 s
766 KB 0.2 s |

Except that the PMR process is not designed for handling performance issues in general.
Nor will bprasana be able to open a PMR on v6.0 if bprasana waits more than two weeks. |

Actually, I just tries with 6.1. That has the same issue too!
Let me try to raise PMR. If not for performance I could atleast ask for some bench marking results I think.
Thanks for the replies. |

You can certainly ask.
But the PMR process does not cover performance issues.
The Performance Report SupportPacs provide a lot of benchmarks. |

I presume that's a typo!
Have you tried running this standalone, i.e. not in a node and not in WMB? Might be interesting |

Sorry, yes that was a typo. I wasnt able to copy from remote machine so i typed that whole thing 
You mean through some other parser? - I have not tried it. Do you recommend any? |

Various Transform classes in java, e.g. XMLUnit's
org.custommonkey.xmlunit.Transform
You could run it outside WMB, and then in a java node for the fun of it!  |

| I tried this in RAD which comes with default XSLT parser. Only the first one took more time subsequent transformations took no more than a second. |

What other nodes are in your flow and what method are you using to time/measure performance?
I have run hundreds of performance tests on XSLT node on v6 and v6.1 and to my knowledge there is no performance issue. Sounds to me like you have trace and/or debug enabled on your flow or execution group. I would suggest you check these. Measuring performance of the flow with trace nodes in and enabled is also no advisable.
For a sanity check try running the xslt sample from the samples gallery, the input message is included, this is the same benchmark flow used in the performance reports so we know its sound. This will help validate your environment. If you want a tool to drive the flow to measure performance then look here:

Hope that helps |

Hi,
It did not help much. Also the CPU utilization of that EG is varies from 50- 75% in topas.
I loaded about 1K messages using the tool you send above using mqjava.Sender.
I did not understand the output. But i checked the time taken by looking at the increase in msg count. it still is about 2-3s for a that simple transformation.
I also checked the EG for any trace or debug, there is nothing set on it at the moment.
Do you have any suggestions?
Thanks
