Jimmy's cloud9 library is primarily for educational use - it's free to include (license-wise), but not all of the classes in there are performance optimized, including this one. I don't think he's even benchmarked this against gson or jackson, but I can ask him (he is on leave from UMD and working at Twitter this year). Regardless, I agree with Sean - we pulled json *out* of mahout for a reason, let's not bring it back in. -jake
