I have done my part of analysis and even know where it is taking time. So I am left with 2 options 1) Splitting the large XML file to small chunk of files based on a condition. 2) Increasing the DTM threads in Java API so that compiled version of Xalan can be used. Let me know if you have any ideas in one of the options above. I can ask questions to the point on the option you say

I have asked specifically what sort of information I should update here which is required for your analysis as I don't know what logs, JVM settings , XSL snippets which is taking more memory and time you may require for your analysis.If you have asked me any one of the above details or whatever you think is required, I can definitely provide them at first place.

I have done my analysis and I guess you do not understand actually what the issue is.Do understand am not a kinder garden student to just post a question and expect a ready made answer as I have done quite a lot of research in it more than you . I will look for someone who can just help me out on what are the different parameters that can be looked for rather than just replying generic. Please do not bother to reply further. Thanks again.

Hi, Thanks for the reply. Answer is no , to the people whom I have checked with was not able to diagnose where the problem is and what is the way around it. Everyone definitely understand that the volume of data in the file is huge , say 100MB xml document but no one till data have given a way to work around it efficiently. Let me know if you wish to have a glance and will look forward to your suggestions

Hi All, Feels good to be a part of this forum of technical stalwarts and Gurus. I feel I will get a solution for my long time problem here . The problem we are facing here is the performance issues when processing the large XML files. Using Java API transformer factory in interpretive mode takes unbelievable 6 days for processing huge files which is a point of very serious concern in a production system. Please help me out and do let me know what are the different things required to be attached which will be helpful for the analysis.
