[libxml-devel] Memory usage compared to REXML

[ileitch]

Hey,

I just switched over a chunk of code to use libxml-ruby expecting to
see improvements in performance and memory usage. While performance is
drastically better, memory usage has increased quite significantly.

With REXML parsing a 3.8mb document would consume 259mb, however with
libxml-ruby parsing the same document consumes around 407mb.

Is this expected or am I doing something wrong? I've tried niling
objects and starting GC at various points in my code but to no effect.

I'm using 0.9.8 on OS X.

Thanks
Ian
