Benchmarks Of The Btrfs Space Cache Option
Phoronix: Benchmarks Of The Btrfs Space Cache Option
In early November we delivered benchmarks of EXT4 vs. Btrfs on an early Linux 2.6.37 kernel as our latest round of tests comparing these two leading Linux file-systems. There were some changes in the Linux disk performance with these file-systems using the latest Linux kernel code, but overall it was not too interesting. However, as the Linux 2.6.37 kernel does introduce a new mount option for Btrfs, the space_cache option, we decided to explore its performance in today's article.
OCZ Agility EX vs. OCZ Agility II EX
In this test is used OCZ 64GB Agility EX SSD. I believe it uses older Indilinx controller. The new Agility II uses SandForce SF-1200 controller. By default SF-1200 compresses the data before its written to the flash memory. So during the test suggested by ChrisXY I would love to see inclusion of SandForce based SSD. It will demonstrate how effective the compression option is when compression is done by SSD's controller.
