Sriram. I can comment on that link (my name is in there somewhere!). Yes, the SUN JRE had some horrible synchronization performance "bug". It made it really excellent for finding code in Xalan-J that did synchronization, and cleaning up many of the places that used synchronized methods, but didn't have to. I worked with Toadie and flushed out many of those spots. Those changes all went into Xalan-J 2.7.1
Which JREs are you using, and which version of Xalan-J? Still, the pressure needs to go to SUN to fix how it handles synchronization. - Brian Sriram83 <[EMAIL PROTECTED] com> To xalan-j-users@xml.apache.org 09/16/2008 10:47 cc AM Subject Re: XSL Transformation in Xalan - Pls help! Michael: yesterday, we stripped the xslt transformation component seperately and executed the xslt transformation for about 1000 transactions. But still, there seems to be difference between execution time in windows vs execution time in linux box. Also, we came across this post regarding Xalan in multicore environment.. Can anyone provide comments on this post? http://marc.info/?l=xalan-j-users&m=117327580321384&w=2 Regards, Sriram. Michael Ludwig-4 wrote: > > Sriram83 schrieb: >> 1/.
