Grant Ingersoll commented on MAHOUT-65:
---------------------------------------
So, with Sean's patch to MAHOUT-121, it seems the bottleneck is now in
deserialization. In looking at it, it seems like there is a whole lot of
String stuff going on. In particular, line 61:
{code}
String vector = obj.get(VECTOR).getAsString();
{code}
seems a bit worrisome. I haven't looked into GSON yet, but is there any advice
on making it faster?
