The Linux 3.0 Kernel With EXT4 & Btrfs

With the FS-Mark program handling 1000 files of 1MB size, EXT4 led on both systems. With the Sandy Bridge notebook with Intel SSD, EXT4 was 34% faster while it was just about 15% faster with the HDD-based ThinkPad.

When this FS-Mark test profile was run again but with sync/fsync enforcement being disabled, the performance between the two file-systems was close to the same with only a slight advantage to Btrfs on the HP EliteBook.

Running CompileBench on the Intel solid-state drive system did much better atop EXT4 than Btrfs. The slow hard drive system's performance was close to the same between the two file-systems.
