Phoronix: Btrfs File-System Tuning Benchmarks On Linux 3.9

For those of you wondering the performance impact of using mount options for tuning the Btrfs file-system on the soon-to-be-out Linux 3.9 kernel, here's some benchmarks of common Btrfs mount options...

Snappy?

Does it support Google's Snappy compression?

I'd be curious to see the CPU and RAM usage difference when doing these exact tests. Also, I'm curious how different the results will be with compression and discard on at the same time. Depending on the results, I might switch my SSD to btrfs.

Hm, I see the 3.8 kernel in the openbenchmarking.org results, not the 3.9. Btrfs from 3.9 has several performance optimizations which worth testing.
