OFBiz uses a lot of XML files. When each XML file is read, it is first parsed
into a DOM Document, then the DOM Document is parsed into OFBiz Java objects.
This two-step process consumes a lot of memory, and it takes more time than it
should.
There is an alternative - what is called event-driven parsing. The XML parser
can be set up to convert XML elements directly to the OFBiz Java objects -
bypassing the DOM Document build and parse steps. Theoretically, this could
provide a huge performance boost, and it would use less memory. In addition, it
would solve the problem of huge XML files maxing out server memory during the
parse process - like with entity XML import/export.
Has anyone else considered this? Do you think it is worth pursuing?
