Bug description: Long and memory-intensive processing handling .Net response
with datasets
Description:
------------
We have been doing performance tests with PHP and .Net interacting through
web services. As a test, we have a .Net service returning a dataset with
100000 entries, which makes a SOAP response of about 25 Mbs. We also have a
PHP service returning the same data but simply as a string containing a
base64-encoded XML (this makes a SOAP response of about 30 Mbs). I have
written a test client that simply calculates how much time it takes to call
the service and get the response. When calling the PHP service, it takes
about 22 seconds to run, which is fine given the amount of data. However
when calling the .Net service, it takes over 4 minutes to complete and the
process' memory usage gets over 200 megabytes, even though the response is
smaller than the PHP service's. I am pretty sure that this has something to
do with processing a large XML (maybe converting entities?).
Reproduce code:
---------------
Simple client:
$soap = new SoapClient("http://somewhere.com/test/service.wsdl";);
$start = microtime(true);
$soap->SomeTest();
$end = microtime(true);
echo ($end - $start);
