ostrstram vs. message callback function

[mvasicek]

Hello Dave,

I would like to ask a question. You wrote:

"...By the way, transforming to an ostrstream can be extremely inefficient.  I suggest you take a look at the callback interfaces in XalanTransformer, which will allow you to get the results of the transformation directly, rather than writing it to a dynamically allocated string.  The performance improvement will be considerable."

I did a simple test on HP-UX 11. I performed 100 transformations using XalanTransformer.transform(), where the output was either ostrstream or a callback function. The difference was less than 5%. Is your experience different from mine?

Best regards, Miro.
