Andrew Purtell commented on HBASE-11927:
----------------------------------------
I wonder if we could make this pluggable. There are other non-ASF options like
Cloudflare's SSE optimized native gzip
(https://github.com/cloudflare/zlib/tree/gcc.amd64)
> If java7, use zip crc

> Up in hadoop they have this change. Let me publish some graphs to show that
> it makes a difference (CRC is a massive amount of our CPU usage in my
> profiling of an upload because of compacting, flushing, etc.). We should
> also make use of native CRCings -- especially the 2.6 HDFS-6865 and ilk -- in
> hbase but that is another issue for now.
