Bonnie++

About

bonnie++ is an open source tool that can be used for testing the hard drives(storage devices) and filesystem for performance. Supports-

• Command line options to specify number of files, file size to be used in performance tests.
• Option to enable fsync() after every write to avoid any write buffering.
• Performance numbers for create, write, rewrite, read, sequential read/writes and random read/writes.

Visit bonnie++ man page for more information.

Source Download Location

• Visit Download bonnie++ from sourceforge

Cross compiling

• Cross compilation command - make CXX=$(TOOL_CHAIN_PREFIX)-g++
  • The TOOL_CHAIN_PREFIX corresponds to the tool chain in use. Set this based on your tool chain. Also make path to toolchain is exported as part of $PATH.

Test setup

• EVM booted up with NFS configuration.
• Connect a MMC/SD card to the MMC/SD slot of the EVM.
• Format the card with vfat and ext2 partitions.
• Mount and run the performance test on the card with VFAT and ext2 partitions.

Execution

./bonnie++ -d /tmp/foo/ -u root -s 1 -r 0.5 -n 1

NOTE-

• -d scratch-dir  : Write scratch file in named directory (default: "."). Filesystem must be large enough to accomodate the size of the working file.
• -s size-in-Mb  : how many Mb to use for testing (default: 100)
• -n  : Number of files to use for test
• -r : system memory(ram size).
