Testing Btrfs On The Linux 3.16 Kernel

I've been using btrfs for all my file systems for almost a year. Here's some general advice:

• Programs which use large files will be a bit slower, especially if you take regular snapshots. e.g. Chrome, virtual machines. Consider disabling COW on these files (chattr +C), or keeping them on a different file system. Note that this effect is largely negligible on SSDs.

Oh wow, thank you for this. My VirtualBox performance has been horrible and chattr +C on the VDI file fixed it!

No problem. Actually, a related issue I had recently was Chrome being horribly slow, since btrfs increased its cache's latency. Mounting ~/.cache/chromium as a tmpfs gave that a pretty big boost as well.
