Log-structured file system for Linux 2.6

Multithreaded measurements including fsync of LFS with roll-forward and ext3

IOzone is a file system benchmarking tool available from www.iozone.org capable of measuring wide variety of file system operations on many platforms. This page contains graphs comparing the performance of LFS with roll forward and ext3. Operations performed concurrently by 8 threads. Measurements do not include the fsync operation.

The computer used in this experiment was an AMD Athlon(tm) XP 2500+ with 256MB RAM with two SATA disks. The measured file systems always resided on a 80GB Seagate Barracuda while the rest of the system was placed on a 120GB WD. Note that the maximum file size is twice the available RAM.

Raw data of LFS are available here. Raw data of ext3 are available here.
