---------------------------------
Thanks Boris, I downloaded the source, and compiled in windows, search around
the change you have made and it looks good to me. It would be nice to include
in one of the test sample, so people realize there is a feature of this. I see
10% memory footprint reduction in my case, and saved me running ove 2GB limit
in windows.
> Configurable kInitialHeapAllocSize in xerces
> ---------------------------------------------
>
> Key: XERCESC-1821
> URL: https://issues.apache.org/jira/browse/XERCESC-1821
> Project: Xerces-C++
> Issue Type: Improvement
> Components: DOM
> Environment: All OS
> Reporter: george
> Assignee: Boris Kolpackov
> Priority: Minor
> Fix For: 3.0.0
>
> Attachments: DOMDocumentImpl.cpp, DOMDocumentImpl.hpp
>
>
> The default DOM initial heap size is 16k in the latest release (earlier
> release was 64k). this number could be still too big or too small for some
> system.
> The idea is to make the following parameters configurable in the constructor
> via a singleton read function.
> static XMLSize_t kInitialHeapAllocSize = 0x4000;
> static XMLSize_t kMaxHeapAllocSize = 0x20000;
> static XMLSize_t kMaxSubAllocationSize = 0x1000; // Any request for more
> bytes
> Now the question is if you think this is a valuable suggestion? I have a
> working code and would like to share if you think it worth the effort.
> Cheers
> George
