Dave tests compression

Dave from Fishworks has tested ZFS compression on the Sun Storage 7000 series. This is just a simple test, but interesting to see that performance improved slightly when using the LZJB compression algorithm. Compression relieves back-end throughput to the disks, and the LZJB algorithm doesn't consume much CPU to do so. I had suggested trying compression this in my streaming disk blog post, but didn't have any results to show. It's good to see this tested and shown with Analytics.
