 Description   

Snappy provides 64-bit optimized functions. But in 1.1.3 release these functions are only enabled for x86-64 (K8) while they should alsow work on PPC/ARM64.
The benchmark result from Chromium shows that with 64-bit code path enabled, the performance have pretty much increasement.

Hey jun.he,

We are in the process of upgrading snappy to 1.1.7 now which will by default pull in these performance optimizations that are applicable.

I'm going to close this as a duplicate of that ticket, thanks for bringing this to our attention!
