Subject [jira] Commented: (XERCESC-1821) Configurable kInitialHeapAllocSize in xerces
Date Fri, 19 Sep 2008 02:30:44 GMT

    [ https://issues.apache.org/jira/browse/XERCESC-1821?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12632488#action_12632488

george commented on XERCESC-1821:
---------------------------------

One additional comment,  I still fell it would be nice to have a configuration file.  I have
hundreds of DLLs in one project, and it would be a a big effort to add this change into all
these components, or the feature will never be used.  sorry being stubborn

> 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
