Xalan Tranformation Running Slow after about 5K Transformations
Hi all,
My java application (running in "Java HotSpot(TM) Server VM (build
14.0-b16, mixed mode)" on Sun Netra T5440) using Xalan transforms
thousands of XML files (uses 16 Threads). After it transforms about 5000
XML files, it becomes slow and it starts transforming very slowly and it
takes 2mins for some transformation (where the first transformation of
similar XML with same XSLT ran in just 2 secs). One of the Thread Dump
is as follows
java.lang.Thread.State: BLOCKED

- waiting to lock <85094f> (a java.util.Vector) owned by

I couldn't find any bug other than 2336 and 2344 that talks about
Vector. Please share any info, by which I can achieve consistent
performance.
Thanks in advance,

What do you mean by releasing cached information?
I have only javax.xml.transform.Templates cached and the newTransformers
are created in method scope of threads and those references are not
maintained anywhere.
Ok.. I forgot to add one important information. My application was
running smoothly for any number of transformations without any issues
previously. I'm facing this issue only after I have included EHCache
library in my application to store the XSLT output. Have any idea where
these two conflicts?

Yes, it's the user's responsibility to release cached information, when
it's no longer needed, by discarding the Transformer.

Hi Gary,
Yes. I got the issue root cause. It's the EHCache library configuration.
Thanks for all who spent time reading & responding to my emails.
With regards,

It sounds from an earlier email that you problem was introduced by you
cache. I suggest that you figure out if this layer causes the problem
and if it can be configured to get the behavior you want.

Hi Gary,
I'm using VisualVM to monitor my application. I am taking Thread dumps

what eats my memory. But, I don't understand how to analyze this issue
by seeing the memory as my application has cache that eats more memory.
Any input like the classes' instances to be looked for will be helpful.
Thanks in advance,

Yes. I always create a new Transformer from XSLT's Template Object for
every new thread that is spawned.
I'm wondering why the first few thousands of transformations are running
smoothly and then the performance degrades!

If I recall correctly, TransformerImpl is not threadsafe, and should be
used for one transformation only.
So, for each distinct stylesheet, you should have a Templates object,
used to create a Transformer for each use. Then there should be no
contention for anything used by the Transformer.
