Hi list,
I don't trust theoretical benchmarks that much and prefer "real-life
benchs" on the occasion, so here's mine:
Given 4 laptops, the most powerful of which was running BTRFS and the
others ext3 or ext4, all machines running Ubuntu 11.04 Natty 32-bit with
a stock Ubuntu 2.6.38-11 kernel, all machines were given the following
FS-intensive task :
- Upgrade O.S. from Ubuntu 11.04 Natty to 11.10 Oneiric (beta), using a
local packages apt-cacher.
Machines :
1/ Acer Aspire 3104 WLMi, AMD Sempron Mobile 3500+ @1.8 GHz, 1.5 GB RAM,
80 GB SATA HD, ext4 over standard partitions
2/ Asus EeePC 1005PE, Intel Atom N450 @1.66 GHz, 2 GB RAM, 250 GB SATA
HD, ext3 over AES-128 encrypted LVM
3/ Compaq Mini CQ10-740SF, Intel Atom N455 @1.66 GHz, 1 GB RAM, 250 GB
SATA HD, ext4 over standard partitions
4/ Dell XPS M1330, Intel Core 2 Duo T9300 @2.5 GHz, 2 GB RAM, 160 B SATA
HD, BTRFS over AES-128 encrypted LVM
Results :
All 3 ext3 / ext4 machines took between 60 and 90 minutes to complete
their upgrade.
BTRFS machine took 20 HOURS so far, still counting (ETA 15 minutes left).
Wow. Impressive.
