> I'm doing some tests with invokation of BPEL service with large
> input/processing data. The data is simple xml with large text content. There
> are some places, where BPEL process runs very slowly. They are:
> - bpws:doXslTransform function. Invocing two functions with about 14 Mb of
> data like this
> bpws:doXslTransform("../common/modify.xslt",
> bpws:doXslTransform("prepareData.xslt",
> $validateSignatureResponse.parameters, "processingData", $processingData),
> "descriptor_file", "descriptor.xml", "transaction", $transaction)
> takes almost 8 seconds.
> - ASSIGN activity itself for every variable resulting large data takes 4
> seconds.
> With elcipse tptp I found some bottlenecks in code. After optimizations
> ASSIGN activity takes 0.016 seconds, and transform takes 0.203 seconds. The
> proposed path follows. This path is made against 1.2 svn tag, but I think it
> can be easily ported to 1.x branch etc.. It works for me with XPath 1.0 BPEL
> language, other languages should be tested.
