问题
I am using isaacs' SAX to parse a huge xml file. Also recommended by La Gentz.
The process uses about 650M of memory, how can I reduce this or allow node to use even more.
FATAL ERROR: CALL_AND_RETRY_0 Allocation failed - process out of memory
My XML file is larger than 300M it could grow to 1GB.

You should stream the file into the parser, that's the whole point of a streaming parser after all.
var parser = require('sax').createStream(strict, options);
fs.createReadStream(file).pipe(parser);
