Hi everyone,

This is dm-ioband version 0.0.4 release.

Dm-ioband is an I/O bandwidth controller implemented as a device-mapper
driver, which gives specified bandwidth to each job running on the same
physical device.

Changes since 0.0.3 (5th February):
   - Improve the performance when many processes are issuing I/Os
     simultaneously. 
   - Change the table format to fully support dmsetup table/load commands.
     The table format consists all configuration parameters.
   - Port to linux-2.6.25.

An administration tool is available. It makes it easy to configure
bandwidths of disk partitions.
You can download it and find the manual at
