bandwidth

Bandwidth is primarily a memory bandwidth benchmark, but as of release 0.24a, it can also measure network bandwidth. The memory benchmark measures the maximum memory bandwidth of each part of the memory system, including main memory, L1 and L2 caches, framebuffer memory, and register-to-register. It does this using fast, sequential memory accesses. It also performs random memory accesses to provide a more real-world performance estimate. The memory bandwidth tests support Linux (Intel and ARM), Windows/Cygwin, Mac OS X, and Windows Mobile. Its core routines are in assembly for x86, Intel64, and ARM architectures. Bandwidth also includes automatic graphing of the results, stored to a BMP image file. The network bandwidth tests support Linux, Mac OS X, and Windows/Cygwin.
